Restaurant chain Pizza Hut has been forced to apologise after one of their branches in Singapore described a customer as a “Pink Fat Lady” in a handwritten note on her receipt. Aili Si posted on Pizza Hut Singapore’s Facebook page on Sunday, sharing a photo of the receipt and saying she felt insulted at the description. She wrote: “I don’t think it is nice for your staff to describe me as such on my receipt.” “As a customer I definitely hope to be treated with basic respect deserved by any others. I hope to receive an apology from the staff and Pizza Hut.” “Just feel insulted. What’s wrong being plus size? I’m a customer n I pay for my pizza! Not that I’m get it for free!” [SIC] Pizza Hut responded to the complaint on Monday night, saying: "Pizza Hut Singapore would like to apologize unreservedly to Ms Aili Si for a recent incident that took place on 12 Oct 2014 at 6.01pm. This incident goes against our corporate values and we do not condone behaviour or actions that offend people." "We are currently investigating this matter.
