A hooded armed robber bursts into a bank.......

Got this in an email today


A hooded armed robber bursts into a bank and forces the tellers to load a sack full of cash.
On his way out the door with the loot one brave customer grabs the hood and pulls it off revealing the robber's face.
The robber shoots the guy without hesitation! He then looks around the bank to see if anyone else has seen him. One of the tellers is looking straight at him and the robber shoots him also.
Everyone by now is very scared and looking down at the floor.
"Did anyone else see my face?" calls the robber.

There is a few moments silence, then one man, raises his hand and says "I think my wife may have caught a glimpse..."
