Found that out on my way to PIR on OCT 27th. Got out to fill up the car and 'some' guy is asking what I wanted and started to open my gas cap. I was ready to punch this guy and say stay away from my car, but luckily for him I glanced and caught the "full-service" sign on the pump and let him slide.
Then looked for a self-service one and saw it was full or nothing. Kinda wierd when you don't see it coming. Are you supposed to tip those guys too?
