A girl in my class did that. We we're lining up to get on the bus, and one of the girl's friends went, "Oh, I'm saving a spot for her, she's the birthday girl." and cuts us all. Then, I get on the bus, the birthday girl takes the seat for the handicapped students (even though we have none) which is at the front of the bus. I hate people like that, that think they're the most superior beings on this planet while it's their birthday.
EDIT: Made it a little less vague.
