What’s the dumbest thing a table has ever complained to you about?

I once had a lady who complained that the coffee was cold. I brought her a new cup with hot coffee and apologized and she got mad at me for that and told me “you don’t need to try to fix everything” like what? And then when she was checking out she told me “you’re not doing a very good job” all over some coffee y’all.

Then another time I had customer complain about our tipping percentages she said and I quote “why are your tips so high? Why should I give you $7?” I said “ma’am you don’t have to there’s an option for none if u wouldn’t like to leave one at all or custom if you’d like to leave less”. She left $3, which was nice but it seems like she wanted some kind of reaction bc she low key looked taken aback that I told her leave nothing.
