I suspect that few people grow up wanting to be gas station attendants either. I grew up wanting to be a test pilot, that didn't work out but I am certainly in my current field entirely voluntarily.
As far as I know, there are no documentaries made about how it sucks to be a gas attendant.
Maybe that means it doesn't suck to be a gas attendant, or maybe that means everybody knows it sucks to be a gas attendant, or maybe that just means that nobody gives a shit about gas attendants at all.
