I also want to apologize for my group. Because we were new to the situation, our 13-year-old minds didn’t really know how to handle the bill. You were very helpful in splitting the bill and accepting our cash.
The bill was fair, but we had totally forgotten (and honestly didn’t know) what a tip was, or how much to leave. So we checked our pockets and found we had a total of $3.28.”
