I've been rather lucky in terms of service and food.
My dining partners, on the other hand...
My father is a complete ass to people who work in food service, even if they're polite and trying to do their best.
We were once at a seafood restaurant and were about to sit down at a table when a booth was vacated [there were still plates and glasses, etc]. My father proceeded to ask for the booth and started being a jerk to the [rather cute] waitress, since the booth wasn't cleaned the instant he asked. He was rude to her for the rest of the meal -- demanding instant service and complaining that the food took too long to get there [20 minutes].
This worked out to my advantage, however -- after my father left the restaurant, I slipped her a tip and she slipped me her phone number.
