yeah that too, he was talking about getting in fights in the bar at the hotel. i’m thinking: the hotel is 300 a night for a standard room who the hell you fighting with the rich businessmen?
You should start talking to someone loudly and imitate him. Make up topics of your choice to brag about, preferably things that are really lame, just to be more sarcastic. If there is no one else to talk to, feel free to substitute a cell phone that you haven’t actually dialed.
Hopefully he’ll have a sense of humor. Or he may try to kick your ass. Hard to say. Either way you make your point that he’s a douche.
