"Beer Bar" joke

Banta walks into a bar for a beer and takes a seat. However, just as the bartender put the beer on the bar, there was a loud disturbance outside. Hey ran out to see what was going on but soon went back to drink his beer.

When he got back he found his glass empty and a note saying: "Thanks for the beer!"

Banta was a little ticked-off but ordered another beer anyway. Again, just as the bartender put the beer down a loud crash was heard in the street. Thinking that someone ran into his parked car, Banta runs outside to check on things. Seeing that his car was okay he returned to the bar and again found his glass empty and another note that said: "Thanks again, this was as good as the first one."

Well he still hadn't had a beer to quench his thirst, so he ordered another. Just as the bartender put the beer down, a series of shots were heard outside. This time Banta wasn't going to lose his beer to anybody. So he spit into the beer and left a note saying, "Enjoy, I just spit into the beer." He then ran outside to see what had happened.

When Banta returned he was delighted to find that his beer was just where he left it.

However this time the note said: "You enjoy, I spit in it too!"
