What is it that you truckers want when you stop to refuel?

You stop in town obviously for fuel, food, shower and sexual company. If you stopped in a town that offered some kind of back/spine relief, would you pay for it?

Not a chiropractor, a place where you can get back relief and pay $15-$20 bucks? If you could take anything with you on your road trips, what would it be? What is it that you truckers want?
