Post office too. Really any government office where the public is allowed inside.

Underpaid workers trying to explain bureaucratic minutiae (for which they are not responsible) every single day to people who are not versed in that minutiae, do not want to learn it, cannot learn it, and are preemptively frustrated that they have to have this interaction in the first place. There is no winning--mental health isn't cheap, do the workers' resilience only lasts for so many years/months/days before they default to hating the clients, and the clients don't trust publicly available instructions, thus dooming themselves to the shitty interactions.

The only way to fix this is to take both people out of the equation--preprocess everything that might need to happen for everyone, to the point of turning every transaction into a single trasaction. That requires for every city, county, state, national, international agency to federate, so that you never have to file multiple documents to do a thing.
