Yes, it might seem weird (I'm talking about the job), but when we lived in Ireland (2004-2006) it was a big issue. A social worker came to visit me, when I just came. Apparently there was a rule to visit a person and inform about all the rules: how to get your social card or however it was called (Irish version of green card), what to do if I want to get social security (unemployment benefits), how to get in line for government housing etc. So the guy told me that there's a huge issue with Irish people not willing to work but trying to cheat government out of the money (don't want to go too much into details about it) so many employers were pressured to hire Irish. But that wasn't the only issue. Unless a place had foreign owner, many public places had irish only employees. When we came to US it was surprising and reassuring, in a way, to see employed people with all kinds of accents.
As for the culture questions, they don't really bother me that much. But to be honest, I prefer to talk about it online (here, for example). It's hard for me to respond when somebody on the street suddenly starts asking question about Russia. Usually it starts like,"I hear you have an accent. Is it Russian?" And then, "I've been to Russia", " my son's wife is Russian", "my wife's friend is Russian" etc.

and then an avalanche of questions follows. In these situations I just want to escape as soon as possible

It's sort of like when a random person talks about Autism

All those unexpected conversations make me feel very uncomfortable.
