Bullshi*. A 15% tip is the norm. A 20% or more tip is for above the norm. These servers might make $2 an hour and depend on tips for their livelihood.
“Bullshi*.”
I disagree... Tips are only appropriate for good service.
So if you get lousy service you are required to Tip? I disagree a Tip is for the level of service you receive or you perceived you got.
It’s all in the eyes of the beholder.
