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.
