To escalate, or not to escalate, that is the question!

There was some excitement at the bank in the Wal-Mart Superstore today. I witnessed a man shouting angrily at the two bank employees (it was Sunday, so only two employees were on duty). Both employees were females. One of them demanded that the man leave the store. He continued yelling at her at the top of his lungs. The bank employee, who had asked him to leave, abruptly walked around the counter toward him. He slowly walked toward the exit, continuing to shout angrily. The other bank employee actually beckoned for him to come back, ostensibly so she could get a piece of him! The man left the building, with the first bank employee walking behind him all the way to the exit.

The lack of fear shown by the two females was impressive. However, I could not help but think that de-escalation, rather than escalation, might have been the prudent course of action. I could just visualize the man going home and getting the gun he has always wanted to shoot somebody with, then returning to the store to fulfill his fantasy; and I don't know whether there was or would be anyone in the store with a concealed carry permit.
