Is this necessarily a bad thing? Let's take the gas pump for example. I care far more about me getting out of the gas station and on my way then the attendant. I also don't have to help a particularly whiny customer before starting my car.

I can tell you I get done a lot faster when I jump out of my car and pump my own gas, versus waiting for the attendant (Except I technically break the law every time I do so, thanks NJ!)
