Pizza Hut Singapore issued a public apology to a customer whose takeaway order Sunday came with two pizzas and a receipt with a handwritten note that identified her as “Pink Fat Lady.” Pizza Hut says it is investigating the matter.

“I don’t think it is nice for your staff to describe me as such on my receipt,” customer Alli Si posted on the company’s Facebook page. “As a customer I definitely hope to be treated with a basic respect deserved by any others.”

Her request for an apology was quickly granted by Pizza Hut, which promised an investigation and an assurance that the company does not condone this type of behavior.

“I appreciate Pizza Hut’s effort in addressing this matter and handling it in the best possible way they can,” Si wrote in a public post.

This isn’t the first incident of a restaurant having to apologize for offensive remarks written on receipts. Papa John’s had to apologize for an employee’s racist remarks after a customer posted a receipt identifying her as “lady chinky eyes” on Twitter.

A New Jersey woman filed a lawsuit against CVS for $1 million in 2013 after a cashier identified her as “Ching Chong Lee” on her receipt.
