Actually, most gas attendants in the US don't actually pump your gas for you - almost every gas station here is self-serve now, with the glaring exception of Oregon and New Jersey.

Oregon's state government (have no idea about New Jersey), in an effort to provide more lower-mid level jobs, passed a law a few years ago that required that all gas stations were full-service, which meant that all gas stations had to staff more people to reintegrate full service, which includes gassing up customer's cars. It's a strange way to try to stimulate the economy, but ... I guess ... whatever floats your boat.
