Should I be upset?

[Eastshire]

I arrived late to a game this year because I misread my schedule and had the wrong start time. I was more embarrassed than I've ever been in my life. I tried to insist that I not be paid but the AD wouldn't hear of it.

If you are late for any reason within or outside of your control, you have not earned any money for the game. To even suggest otherwise demonstrates a shocking sense of entitlement. Despite this, some schools are generous and will pay you any way. Any pay in this situation is a gift you should be grateful for, not a slight.
