They feel they got dealt a bad hand. You don't whine at the Blackjack table and I think that applies to arbitration as well.
Gaming ediquette:
Do not ask for pity if you have a bad hand, it happens to everyone. Numerous times I have seen a player hit a stiff hand in blackjack and get an additional small card but still be in the 12-16 point range. When this happens some players will often show their cards to the dealer, make a big sigh, and expect some sympathy for having to make another decision. Nobody cares about your hand but you, make a decision quickly and do not hold up the game.
The Nic was more like roulette. Your career on the spin of a wheel.
