"I ordered a sandwich for $12 and a medium drink for $2.50, which should total $18.50, but he charged me $18.40 instead. I know how to do basic math. Fortunately, the women in the back noticed the mistake and pulled him aside to address it. He then tried to give me a dollar back, but I told him to put it in the tip jar instead. Overall, I won't be returning to this place."
