A man walks into a bar, already drunk, and asks for a drink. "Sorry," the bartender says, "but you obviously already had a little too much to drink."
Fuming mad the man staggers out the front door and walks back in through the side door. “Can I have a drink please?”
“Sorry,” the bartender says, “but you can’t have a drink here.”
The man staggers out again and then stumbles his way back in through the back door. “Can I please have a drink?”
“Enough!” the bartender screamed. “I told you, no drinks!”
The man looks at the bartender closely and exclaims “Geez! How many bars do you work at?!"
