Do you tip for bad service at restaurants?
We had the rudest waitress a few weeks back. She wasn't indifferent, but straight rude. EX: When she sat us down, there was no greeting, but she just tossed a couple menus on the table and walked away. When I asked for a water refill, she rolled her eyes like I was asking her for the biggest favor ever. And when my dish came with something I specifically asked to be excluded, she got angry with me and told me that I should have told her beforehand (which I did!).
I totally did not want to leave her a tip at all, but DH thinks you should always tip, regardless of the service. He thinks the amount is negotiable, not the act of tipping itself.
What do you think?
