Look at the top, left-hand corner at the bill payer's description. 

It happened at Chilly D's Sports Lounge in CA.  When the server returned, the three girls questioned him about the "fat girls" label, but the waiter denied any wrongdoing, according to reports. He said an employee named "Jeff," whose name appears on the receipt, must have typed "fat girls" into the system to keep track of their bill.

A manager went over to explain the "fat girls" check, but he “had like a smirk on his face, like it was funny but trying not to laugh,” Duran told ABC News. Instead of clearing all charges, he offered a discount of 25 percent and then a discount of 50 percent, but the women rejected the offers.

On Saturday, Chilly D's posted an apology on its Facebook page over the insulting bill. (huffingtonpost.com)
