I haven't been doing this for that long but long enough to know that you guys who don't tip the van drivers are the ones who get all prissy when they aren't there IMMEDIATELY when you walk outside, ***** and moan about your pay and how you are broke for four days straight, and are constantly talking about how you need to be paid more.

Karma is a powerful thing. Maybe if you tip the van driver properly, karma will find its way to you and you can start getting more in your W-2s.
