"I had a pleasant experience with the service, and the salsa and guacamole were excellent. However, I encountered a bit of confusion at the register. I handed the cashier a $10 bill and a $5 bill, but it seemed like he wasn’t paying attention to what I was trying to communicate. Even when I repeated myself, he continued to misunderstand. Afterward, I noticed that he took the $5 bill and put it in the tip jar, which left me feeling puzzled. I had thought he was going to input it into the register instead. I’m not great with math, but it would have been nice if he had simply returned the $5 to me."
