When I was on holiday a few years back, the hotel I stayed in was hosting a big local chess tournament. I didn't care for the competition, but the people who were attending it were great entertainment, arguing over the latest top-tier competition matches and basically enthusing about the game with each other. One evening, a particularly egotistical chap had appeared and started droning on and on about how good they apparently were when the shift manager snapped and threw them all off the floor into their rooms or the convention rooms. I asked him why he'd done that when all week he'd been content to let their chatter slide and he replied simply he hated chess nut boasting in an open foyer.
