"Assuming that it's a preconception and not observed is a bizarre assumption."

It's really not, it's basic psychology. People rarely change their opinions based on evidence.

Having said that, in 50 years on this planet and countless interactions with government employees, I haven't had a single bad one. I do try to be kind and accommodating because I know their jobs are often shit and they have to deal with asshats all day long, and maybe that has an impact on how they treat me.
