All drinks on me Jeff, a well dressed well groomed guy, walks in a packed pub, sits at the bar and started to chat and socialise with the barman who happens to own the place. An hour and many drinks later, Jeff asks for a round of shots for everybody in the place, since it's a celebration. He does this three more times, people are on their feet happy, Jeff is having a blast, the owner gets a bit uncomfortable and asks him to pay what he already owes him. Unfortunately drunk him explains that he does not have the money to pay, and that he got carried away, all he has is 5$. The owner takes him outside and beat the living shit out of him, but Jeff escapes before the cops show up. A week later Jeff comes back to the same pub goes to the bar and confidently tells the barman ""Hello, i'd like to buy everyone here a drink, except you, you're a mean drunk..""
