Shell in Marysville (3506 88th St NE)

You have to buy gas or an item in the store before they will give you the key to the bathroom.

nice store and cashier

They have a car wash here. When I went to use a few months ago, it there were no attendants. The clerk/cashier was inside with their feet on the counter and could care less. I was supposed to use the brush myself and guide myself into the automated wash. Very unprofessional and an overall crappy experience.
