I was working the ticket booth in a large theater chain a couple of years ago. I then met one of the dumbest people I have ever seen.
Him : Excuse me...
Me : Yes?
Him : I want a refund on the movie I just saw.
Me : I need your ticket.
I look at his ticket, he went to see "The Day After Tommorow", a movie about the Earth going into another ice age. His movie just finished.
Me : Uh, sir, I can't refund you, you've seen the whole movie.
Him : The movie wasn't what it was supposed to be! I want my refund! (He's starting to get angry)
Me : What do you mean, it wasn't what it was supposed to be?
Him : The movie poster says "By the director of "Independance Day" ".
Me : (WTF...) So?
Him : The movie doesn't have any aliens in it!!!!
At this point I swear I felt a few of my brain cells die. This guy actually thought that The Day After Tommorow would have aliens in it because the director had directed a movie with aliens!
I try to reason with him for a good five minutes until he asks for the manager. The pleading and complaining goes on for another 10 minutes until my manager goes :
Manager : If I refund you, will you leave?
Him : Yes I want a refund!
Manager : I'm doing this not because you're right, I'm refunding you just because I want you lo leave.
Him : I don't care!
My manager gives him back his 10$, and he leaves. Looking back, he might not have been that dumb, beacuse he did get his money back...
