re: Retailer/server employees: worst ever customer?

I waited tables at Ruby Tuesday here in Columbia 25 years ago, I remember 3 basic truths:

1) The closer a party comes in before closing, the less the tip,

2) The messier a party leaves a table, the less the tip, and

3) The more they run your arse, the less the tip.

One night all 3 happened together for a party of 4, they were my only table as we closed the doors and stayed over an hour after. Their check was about $70 and they left me 65 cents for a tip. I was so mad I hurled the change in the parking lot behind them as they were leaving and said apparently they needed it more than I did. I didn't even care if I got fired at that point.
