US gas stations are weird, at least last time I was driving there more frequently (about 5-10 years ago). In my country (UK), some have shops you can go into, but most of the time I for one fill up at an automated pump at the supermarket, put card in, type pin number, fill up the tank, leave. There's no need for anyone to be on site (some do have a store, some are completely unmanned). In the US/Canada when I've filled up, at some places you turn up and someone does it for you, which is a right pain and breaks your train of thought as you have to engage in conversation with someone. Others you do it yourself, but you turn up and find the pump isn't open -- you have to go into the shop and pay in advance, which is just weird - I don't know how much I want to put it, I just want to top it up and then pay the amount on my credit card. I believe laws vary by state or even smaller regions.
