Bank Teller

In a long line of people waiting for a bank teller, one guy suddenly started massaging the back of the person in front of him.
Surprised, the man turned and snarled :
- Just what the hell are you doing ?
- Well, said the guy, you see I'm a chirpractor and I could just see that you were tense, so I had to massage your back. Sometimes I just can't help practicing my art !
- That's the stupidest thing I've ever heard ! the guy replied. I'm a lawyer. Do you see me fucking the guy in front of me ?
