I'm going to give an absurdly low tip to this server.
Why would you give such a low tip?
She was a bitch the hole time and doesn't deserve my money.
It makes sense to not want to reward someone being rude to you. However, she might just be having a bad day and relies on tips to make a living. You don't need to tip her a ton, but at least something to help her get by would be helpful.
Nah, I'm going to punish her for being a bitch to me. What's that bitch going to do about it?
I understand feeling frustrated by poor service, but being cruel won't make things better. I would suggest simply giving a modest tip so she at least gets something. It may brighten her day since it seems like she may be having a rough one.
