This Conversation Doesn’t Fit The Bill

(My family is eating at a large restaurant. My dad is talking to my mom about an unrelated school activity that he didn’t know has fees involved. As this happens, the waitress comes with the bill.)

Dad: “I didn’t know we had to pay for it!”

Waitress: “Umm…”

Dad: “Oh, sorry, not that. I was talking about [school related activity].”

Waitress: “Thanks! You’d be surprised how many people don’t think they have to pay.”
