Today I met a guy who was insistent upon his appointment.

I told him I would check him in but he got mad at me for not telling him that I checked him in late. I apologized and told him that I would check him in, but he was mad I didn't tell him to begin with.

I mean I probably should have told him, and I know that. But what am I gonna do if people are running late and it's out of my control? Nothing.

Anyway, when he left he thanked me. Thanking someone doesn't make being rude ok in the end.
