'I'm not gonna f*cking tip you when all you're doing is taking a cup and handing it to somebody'

[Sancho]

3. I'm going to tip...whether others do or not...even for simple service

Why?

My own experience. My wife and I are older now, and have a good life. She just retired after 41 years of teaching, and I'm still going.

At any rate, we both lost parents early - and we both worked our way through college degrees. As teachers, we also had additional part time jobs on occasion when things were tough. You name it, we probably did it. I remember those days clearly, and how I appreciated every dollar.

I tip for service: valet, dog grooming, waiters and waitresses, hair cuts, delivery, cleaning, helping with the suitcase, etc., etc.

Yes, some are better employees than others, but in general people deserve higher wages than they get (at least in the US). The vast majority of employees are working hard, so no matter their circumstances, I'll tip because someone gave me tips that made my day years ago.
