Restaurants devoted mainly to quick bites and drinks are reconfiguring their businesses to limit traffic in tight quarters and maintain coronavirus social distancing. Starbucks Corp, Dunkin’ Brands Group Inc, Peet’s Coffee and British bakery-cafe chain Greggs PLC have been forced to rethink how to serve customers quickly while keeping staffers safe and still make enough money to operate. At Peet’s Coffee, the US chain owned by JDE Peet’s, 191 of the 250 company-operated stores had reopened as of Thursday. But customers aren’t allowed inside. “We moved all of the tables to the front of the store, blocking the entrance,” said Mary Dusenbury, senior director of retail marketing at Peet’s. Registers and chip readers were also moved to the front, so customers can perform their own credit-card transactions, with chip pads wiped down after each guest. In Britain, where Greggs has been testing reopenings at 20 locations, only one adult customer may enter at a time. The menu features fewer salads, and only credit cards and other non-cash payments are accepted. After closing 2,050 stores in March, it hopes to reopen 800 stores from June 18. The chains aim to keep at least six feet of space both between staffers working behind the counter and between customers lining up at the door. But it is not clear that customers will be prepared to wait in long socially distanced queues outside, even to get one of Greggs’ popular vegan sausage rolls, which had helped fuel an 80% rise in Gregg’s share price before the crisis hit. Companies’ profit margins will be squeezed this year by extra costs for employee hazard pay, cleaning and protective gear, as well as lower sales. That could lead restaurants to raise some menu prices, said Alex Susskind, a professor at the School of Hotel Administration at Cornell University. However, with restaurants having already hiked menu prices over the last few years and cash-strapped consumers likely unable to pay more, “passing along price increases is going to be very difficult,” said David Portalatin, a food analyst at The NPD Group. To keep customers from lingering, chains are encouraging using cell phone apps to order and pay or opting for drive-thru or delivery. In China, delivery and mobile ordering at Starbucks made up 15% or all orders in January when the crisis was spreading. Mobile orders peaked at 80% in February but remained at 27% in late March, according to a McKinsey & Co report on May 19. More than 98% of Starbucks locations are open in China, and more than 90% of its company-owned US locations are expected to be open by early June under modified operations and hours.
