its really weird for someone used to the faster type of gas station. why would people want want to spend any more time than absolutely necessary around petrol fumes...
Because there are no real fumes. No more than anywhere else, and there is more likely to be a gas station with a restaurant (pizza/chicken whatever) in it than a restaurant at all. Small 'town' down the road has one gas station and one cafe. The cafe is only open for lunch. So a lot of the old timers gather at the gas station where they can get a coffee, a snack, or even a chicken dinner, and sit and chat with friends.
