I, for one, would never leave a nickel tip. It's not my job to "teach" the world. Especially considering I don't know if the bad waitress/waiter might just be having a really bad day, like because their dad died the night before and they're doing everything they can just to keep their sh@t together. Also, I'm quite sure the waitress/waiter wouldn't "respect" you more for it, so it really depends upon what you're trying to accomplish in this sitch.
I think you did really well with the response you sent. No more, no less needed. And I believe you WILL have a great weekend. (())
