There’s a reason the word assume contains the word “ass” in it. A guy with a minivan in Atlantic City assumed a man named Steven was a valet and gave him the van’s keys at his hotel. So, Steven stole it and was later stopped and arrested by the police. So the van owner is the first dumbass because how snobby can you be to just look at someone and assume they’re a valet? The thief is the second one because if you’re going to steal a vehicle – a minivan should not be your first choice.
