If a person makes any type of effort at all to take care of our table then I have no problem tipping well. I know their job is hard and they have to deal with rude ass people all the time.

However, if they are rude, never check on our table, then I have no problem giving way less of a tip. Bad behavior should not be rewarded.

The worst I saw was in a pizza place we took our family too a few years ago. The lady sat us at our table, took our drink orders and then we basically never saw her again. And the place was not that busy. We waited forever just to get our order taken and I had to go ask to get someone to come to our table. The lady finally came out to our table and was very rude and acted like we were bothering her to get our order taken. We never got any drink refills. We never got our check. I had to go talk to a guy at the counter to get our check. I did not leave her a tip at all, and I told the manager about it.
