I used to cashier at Wal-Mart. (I lasted 3 months LOL)
Anyway to my surprise, the clients who went through the line were almost always very nice. I was shocked.
Very nice.
Except?
When I had to work the cigarette line. Those people were a different breed. Their skin was grey-brown, their teeth were dark, they had black circles under their eyes and they were ill-tempered and cranky.
Almost half of them fit this description.
So, the CALMING is only when they spent their paycheck to pay for a carton and smoke their tarred brains out. Very soothing if you are mentally stilted.
