Yes...another tipping thread. And an honest question.
Recently I was a guest of my cousin for a lunch.
It was a somewhat busy lunch hour. We chatted away as she ate and I poked at my food (not a fan of this chain). The server was attentive and brought refills and breadsticks without the need of prompting him. He was better than average, especially given the venue and time of day... and we were there longer than most lunching diners would be.
When the bill was paid, my cousin under-tipped - gave something under 10%. Whether it's culture or age or something else, not sure. Not asking about that.
My question is, do you think it's OK to surreptitiously leave extra tip? And if so, what is the best way to go about it? I had some bills in my hand, and when leaving didn't see the waiter and couldn't think of a plausible excuse to return to the table. My cousin, I see a lot. I will probably not return to this restaurant soon (hopefully never). I rathered not offend cousin than waiter, but yeah, he got stiffed and I felt bad. Thoughts?
