Singing in the bar

A man was sitting in a bar and noticed a group of people using
sign language. He also noticed that the bartender was using
sign language to speak to them.


When the bartender returned to him, the man asked how he
had learned to use sign language. The bartender explained
that these were regular customers and had taught him to
speak in sign. The man thought that was great.


A few minutes later the man noticed that the people in the
group were waving their hands around very wildly. The
bartender looked over and signed "Now cut that out! I warned
you!" and threw the group out of the bar.


The man asked why he had done that and the bartender said,
"If I told them once I told them 100 times - NO SINGING IN
THE BAR!"
