SAVANNAH, Ga. — Four customers clutching masks were waiting outside David Huynh’s nail salon as he opened his Georgia business for the first time in four weeks Friday. Nearby, the lights were still off in clothing and jewelry stores closed because of the coronavirus pandemic, and many residents stayed locked inside their homes.

Georgia’s economy began a cautious, high-stakes reopening as Gov. Brian Kemp relaxed a monthlong shutdown amid experts’ warnings of a potential surge in infections and objections from President Trump.

Huynh had 60 clients booked for appointments, and police officer Alina Davis was among them. “Yes, I am ready to get my nails fixed,” Davis said.

Georgia has ranked in the bottom nationally in per capita testing, a key component in preventing a resurgence of the coronavirus which causes COVID-19, and critics say Kemp’s order to restart some businesses was premature despite a bump in screenings this week.

But in metro Atlanta, the Three-13 Salon, Spa & Boutique opened to a line of masked customers whose temperatures were checked before entering. Waiting customers were carefully distanced, their spacing marked by blue tape, and chairs were placed at staggered intervals outside.

Managing partner Lester Crowell said there was some nervousness and anxiety among salon employees. “But you know, we all want to come back to work,” he said.

With deaths and infections still rising in Georgia, many business owners planned to remain closed despite Kemp’s assurance that hospital visits and new cases have leveled off enough for barbers, tattoo artists, massage therapists and personal trainers to return to work with restrictions.

At the reopened Bodyplex Fitness Adventure in Grayson, a dozen people in masks worked out on two floors, spraying down machines and weights with sanitizer provided by the gym. The gym had but a fraction of its usual number of customers, yet some talked and stood close to each other anyway.

“The social distancing I think is probably the biggest challenge,” co-owner Mike Martino said. “I guess when people feel like they have masks, they’re somewhat protected, but we’re still encouraging people to try to stay 6 feet apart whenever possible.”

A young couple bowled at midday in an otherwise empty Bowlero, a 34-lane alley in Kennesaw, kissing between rolls, but the arcade area was empty. Workers wiped down games and other surfaces, and signs about social distancing were plastered everywhere.

Many people are staying put at home.

Advertising project manager Nikki Thomas is overdue for a visit to her hair stylist, but she’s barely ventured outside since her Atlanta employer mandated working from home on March 12, and she had no plans to change that now just because of Kemp’s decision.

“It’s obviously extremely stupid, and I’m simultaneously exhausted and so angry I can barely see straight,” Thomas, 40, said in a phone interview.

The effect of the reopening varied. The president of the Warner Robins chamber of commerce in middle Georgia said more cars were in parking lots, but Waycross City Manager Tonya Miller said she hadn’t seen many businesses open in her southeast Georgia town.

Traffic in Atlanta remained lighter than normal. In Savannah, though a number of salons and shops remained closed, there was plenty of traffic around shopping centers.

Although many businesses never closed, the governor has said it was imperative to begin easing his state’s economic suffering by allowing others to resume work. The Georgia Department of Labor said 1.1 million workers – about one-fifth of the state’s workforce – filed for unemployment since the crisis started.

Although two administration officials told the Associated Press that Trump and Vice President Mike Pence repeatedly told Kemp they approved of his aggressive plan before the president bashed it publicly earlier this week, Trump tweeted a denial as businesses reopened.

“I (or @VP) never gave Governor Brian Kemp an OK on those few businesses outside of the Guidelines. FAKE NEWS! Spas, beauty salons, tattoo parlors, & barber shops should take a little slower path, but I told the Governor to do what is right for the great people of Georgia (& USA)!” the president said in the tweet.

Georgia’s approach to reopening comes amid a global patchwork of measured steps to reviving economies.

In several European countries, the focus has been on reopening manufacturing, small shops and some schools. In many places, restaurants remain shuttered or open but only allowing takeaway and delivery, and in France authorities announced that restaurants, bars and cafes won’t reopen before June.

Just across the state line in Anderson, South Carolina, a mall reopened on Friday after the governor allowed businesses that don’t involve close contact like jewelry stores, clothing boutiques and bookstores to restart.

Public health experts have warned that reopening too quickly could trigger a coronavirus resurgence. Preventing that will require increased testing and robust tracking of infected people’s contacts.

Georgia has more than 22,000 confirmed cases of the virus and 894 deaths, according to state statistics. The state has been lagging in the number of tests per capita, but has administered an increasing number this week.

The reopening will pick up steam on Monday, when Georgia will allow movie theaters to reopen and restaurants to resume dine-in service — as long as customers are kept at a distance.

Chef Hugh Acheson, who owns three fine-dining restaurants in Athens and Atlanta, said Georgia is conducting too little testing to reopen.

“If I open up fine dining in midtown Atlanta and … 25 people show up to dinner because I’m brazen enough to do this, that’s not enough to make money and stay in business,” Acheson said.

Back in Savannah, Ebony Housey of Savannah has mostly been staying home for five weeks, and she booked an appointment with hair stylist Shannon Stafford as soon as she could. Both women wore masks and chatted while Stafford shampooed and blow dried Housey’s hair.

“I’m getting my hair done, and I’m going straight home,” Housey said.

Stafford replied: “Well, when you get home, you’re going to look fabulous.”
