This is my request as a driver for anyone hitching rides.
when riding in someone else's car, have garbage bags for your dirty gear and a change of clothes when you leave the game. Don't stink up your ride's ride. Take your garbage with you when you leave, gas money, offer coffee, anything.
As a driver I understand student budgets, so be up front with the driver on what you can offer. You might be surprised that the driver just says you're even with a coffee or something.
