It does irritate me a bit so many petrol stations are removing the option to pay at the pump. If a supermarket can do it, why can't a fuel station? Besides which, having worked as a console operator I used to love them as at least then I didn't have to watch them like a hawk so they didn't nick off without paying (which is incidentally why those who move their cars closer get watched so closely until you come in and pay).

Personally though - it depended on the situation. Hot days or busy servos and I'd bring DD in with me, if she was asleep and everything felt ok, I'd leave her
