A couple years ago, I took my dad out to his favorite Mexican restaurant for Father's Day. My father explicitly mentioned to the waitress that it was so nice of me to take him out for Father's Day. When the waitress came to take our orders, my dad was waffling between two options (one of which was more expensive), I told him to not worry about the cost since I'd be paying either way. Again, the waitress is standing right there.
We finish our meal, waitress brings the check, and - big surprise - tries to hand it directly to my father. He doesn't take it and points at me. The waitress just sets the check down on his side of the table and leaves. I could hardly believe it.
