The other night at a coffee house, I left my table to meet a friend.  I didn't take my lighter with me. When I returned, a black guy was in my chair.  I guess he thought no one was sitting there.  So I let him know it was my table, and he got up and left.  Then I realized my lighter was gone.  I approached him and asked if he'd seen it.  He was insulted and said, "Contrary to the stereotype white people have, not every black person is a thief!"  I replied, "Contrary to stereotypes, not all white people think all black people are thieves."
