It's a gas station, it's fine. Plenty of pumps and I had used the car wash in the past until they changed it to a garage door that would slide down for the wash. Twice I was behind people who rocked their car before pulling it out and the door would go up slightly and then come back down, trapping the wash-ee. After visiting today, I didn't see the door go up and down, but there was no one getting a wash. If it is the same one, I would avoid it.
The convenience store portion (7-11) has plenty of conveniences. And if you need a cold beverage, a blue Slurpee is hard to beat.
