A man walks into a bar and says, "Give me a beer before problems start!"
After finishing his first beer, the man again orders a beer again by saying,
"Give me a beer before problems start!"
The bartender looks confused.
This goes on for a while, and after the fifth beer the bartender walks up to the man.
"When are you going to pay for these beers?", the bartender asks.
The man answers, "Ah, now the problems start!"
