I used to work at a bar, and in this bar we hosted poker tournaments at night, generally getting about 120 people through the door. The problem we had was that poker ran from 12am-4am. People would show up for poker and start drinking at 7. While generally everyone was pretty well behaved, we once had a huge roided up bloke come in to play. Getting towards the middle of the tournament, and there’s only 40 or so players left.
Roidasaurus Rex comes to the bar and asks for a drink, and I have to decline him service (In Australia, serving alcohol to an obviously intoxicated person can result in the server copping a $5500 fine). He walks back to his table, and continues playing. 10 minutes later he starts screaming at someone across the table, security show up and he picks up the edge of the poker table and flips it into the air, then he charges at the nearest security guard. It was a pretty vicious fight but security eventually got him under control and into a cop car. Roids and booze dont mix.
