In a vacuum that would be fine. But in the current culture that likely wouldn’t overcome the tipping standard/culture and may just drive customers away thinking the prices are too high. Unless you have a huge blatant no tipping sign all over the place.

This isn’t too indigestible as it stands provided the wait staff understand they are likely to only get a tip for excellent service.

But to do this on top of an 11 dollar cannoli. That’s a bit different too. I hope it was like a dozen cannolis.
