Obviously, it's not a money-saver, unless it is bundled with perks like a free auto-checkup (window washing, checking fluids etc.) However, though, in the US, unless someone is sick or old, it's sort of shameful to use it, especially if your a man, though that might be sexist to say. Anyway, in certain other nations, though, full-service is taken for granted, as it was in the US at one time, say the 1950s. Oh, by the way, I'd have to say that full-service should be an option some places, but where I live it is not. It's because there are cases of old people etc. who maybe cannot pump the gas.
