re: How much do you give your service providers for Christmas?

I tip the garbage guys because they are the on time on the dime. Mondays at sunup, Thursdays at 10am. Never had a can in the driveway or the street.

Also - You never know when you may need something picked up that is "non-standard"... It helps if you are nice when it counts. I've also been known to hand out cold bottled waters on a hot hot day.
