Shake Shack is returning a $10 million loan after critics slammed the burger chain for getting money from a program meant to benefit small businesses struggling to survive the coronavirus pandemic.

Six other chains — including Ruth's Chris, Potbelly Sandwiches, and Taco Cabana — have not indicated that they planned to return the more than $80 million they've received in Payroll Protection Program loans.

The $350 billion allotted toward PPP loans ran out last week, before many struggling small businesses received any funding.

Restaurant chains are facing backlash after receiving more than $80 million in coronavirus stimulus loans intended for small businesses.

Last Sunday night, Shake Shack's chairman, Danny Meyer, and CEO Randy Garutti announced that the burger chain would return its $10 million Paycheck Protection Program loan.

Critics slammed Shake Shack for applying for the loan aimed at small businesses that would have a harder time finding funding to stay afloat as restaurant sales plummet. Shake Shack announced the loan the same day it revealed it had raised $150 million in a private-equity offering.

"We are seeing tremendous backlash because hundreds of thousands of small businesses have not gotten PPP loans," Chris Allieri, the founder of communications consulting firm Mulberry & Astor, told Business Insider. "Many have had to cease operations because they can't wait until the next pot of money is approved."

While the PPP loan program was intended to help small businesses keep workers employed during the coronavirus pandemic, the hotel and restaurant industries successfully lobbied for an exception that allows chains with fewer than 500 workers per location to apply for a loan.

Shake Shack is not the only chain that cashed in on the initial $350 billion allotted toward loans, which ran out last week before many small businesses could receive loans. At least six other chains received about $81 million in loans.

Business Insider reached out to these six chains on Monday morning to ask about their PPP loans. None of the chains said that they planned to return the loans.

Here's how much money chains including Ruth's Chris, Potbelly, and Taco Cabana received from the program intended to help small businesses stay afloat and keep workers employed.
