Bank Robbery

A hooded robber burst into a bank and forced the tellers to load a sack full of cash. As he was about to exit, one brave customer grabbed the hood and pulled it off revealing the robber’s face. The robber shot the customer without a moment’s hesitation.
He then looked around the bank and noticed one of the tellers looking straight at him. The robber instantly shot him also. Everyone else, by now very scared, looked intently down at the floor in silence.
The robber yelled, “Well, did anyone else see my face?”
There were a few moments of utter silence in which everyone was plainly afraid to speak. Then one man tentatively raised his hand and said, “My wife got a pretty good look at you.”
