I guess I just don't think there are that many sociopaths out there. And you'd have have to have a pretty perfect storm of getting the same waitress (in a fairly transient workforce) that actually remembers you.

It isn't my fault that resteraunts don't pay their people enough money. I might feel a little differently if the tip actually went to the server. In a plastic transaction, it's up to the resteraunt to give the cash to the server. I imagine they take at least 50% off the top before it even starts to trickle down to the server. It's a scam.

The kid stocking shelves at the grocery works hard. The kid at McDonalds does too. The guy digging ditches for a sprinkler company works hard. Who tips them?

And I'm sorry, I refuse to be extorted because of some urban myth of the gallons of spit that ends up on the steak of some non tipper. Truth be told, if we looked in the kitchen of any resteraunt, we'd never eat outside the house again.
