my comment is dumb or the act is dumb? I agree with you in one case.
If you are smart, and I want to believe you are, then you know your second point is ridiculous. I didn't imply that in any sense. That said, I have given people tips for service beyond what I was expecting, when I could. I'm ok with appreciating people both doing their job and doing it better than others. Sometimes it comes in the form of a thank you, sometimes I refer other people to them and sometimes, I may give them extra money! GASP!
Keep all that money in your pocket...don't let it out...never use it to make someone happier or better or to show appreciation...just hoard it.
In any case, I'll keep on doing what I feel works pretty well for me. So far, I have found it's never hurt someone to tip when I can and when they have deserved it.
