OK, so here to have another opinion. I think tips have gotten too high in the uS. Restaurants are counting on us to pay most of the cost of the wait staff. (not to mention with mandatory tip splitting in many places, that we are also supporting other restaurant staff).
That is not to say that one or two of us can make any difference, but I think we should talk about it.
10% should be enough if the staff gets a sufficient base wage. I feel as if I am trying to stop a speeding train. If we take the whole Penny bunch out to dinner, we often get a mandatory 18% tip. Yes, there is a warning on the menu...sometimes, but that is far too much.
Yes, in the past I've worked in situations where I got (and needed) tips, but this is ridiculous!
