TL;DR Waitress persistently made same stupid joke, so I didn't tip on my meal.

I was working out of town, which meant \~14 hour days and a lot of fast food. One day for dinner we went to a TGIFriday's for something slightly better than drive thru burgers. We were seated and the waitress came to take our drink order. Other guys got waters, I asked "Could I get a lemonade?" She said, "No. \*pause\* Haha just kidding!" She dropped off the drinks and I said "Could I have a straw?" She said, "No. \*pause\* Haha just kidding!" She took our orders and when it came time for mine I asked "Can I have the \[whatever\], please?" She said, "No. \*pause\* Haha just kidding!" When we were done I asked her if I could get my check and she replied (you guessed it) "No. \*pause\* Haha just kidding!"

I don't know if it was the long hours, lack of sleep, or what, but this bugged me. She made the same dumb joke numerous times even though it never got a laugh, and seemed to ONLY make the joke to me. The other two guys got straight answers each time.

When the check came for mine (we all paid separately) the total was like $13 or something. A decent tip on that would be like $3. In the tip line I just wrote the word "NO" and walked out. The two guys I was with disagreed with each other. One said it was too harsh and the other said it was funny. I didn't mean it to be funny or mean, I just wanted to make a point.

AITA?
