If you don't tip the van driver your a cheap a$$ futher mucker. Its a few dollars a day. It's also customary. You get TAX FREE perdium to cover expenses. If you don't tip the van diver you obviously never worked in the service industry.
If you don't carry cash with you you're a dumb a$$. At least $100 just in case. Things happen in our business where you'll wish you had cash with you.
