You did the right thing, don't let anyone tell you different. Some people just don't want to listen to anyone about anything.
I've been in a store when someone stole a womans' car when she stopped for coffee and let it run. (no Baby) She was totally surprised that it happened, and if I remember correctly, thought that it was somehow the stores' fault and was upset at the cashier for not being faster! - (I like that purple guy!)
