Cornell,
Part of Glenn's post says:
"i - I'm not alone in finding 20.00 bills at the bttm of my food. (IF I catch it
I go back and return it. I don't want to get them fired - after all.)"
As I re-read his post I don't believe he is saying to keep the money especially if it is coming from a low level employee like a cashier or counter person. Personally I would always return the cash. I don't want them fired either.
On the other side of the story, the pay it forward principle seems to be a workable principle. At the very least, how can it hurt anyone if you tip a $1 or a $1 lottery ticket.
I've also noticed a smile and pleasant demeanor works on some of the grouchiest bastards in the world. I think those are paying it forward units as well so I use them.
As far as morals and ethics, I'll defer to the politicians for a definition.
Have a great day...
Tom
