There was a world-class Chess championship being held at a hotel in Chicago. On the night before the competition started, the hotel lobby held a reception for the players, spectators, and chess enthusiasts from the area. Well, being such a world-class event, many many people showed up for the reception (and the delicious buffet!)
The only people who weren't pleased were the bellhops, baggage handlers, busboys and waiters. A few of them were standing talking behind the front desk, generally complaining about the whole event. In walked a rather exhausted-looking waiter from the lobby.
"Man," he said "Nothing is more annoying than a bunch of chess nuts boasting in an open foyer."
