Who else is doing it doesn't change the matter. Charging your guests more then your own? You don't think the morally correct thing is to charge them the same?
name one. I have traveled a lot and can’t say I can name one place where this is a thing. the closest I’ve seen is like tollroads that have different payments methods for residents vs non-residents :)
My travels through India frequently charged a much lower price for Indian citizens/residents, vs tourists with foreign passports for tickets to museums/temples/etc. The fee to foreigners was not exorbitant when compared my salary back home but would have been unaffordable to someone earning a local Indian salary.
yea, if you are coming from a sketchy area we may have to do a bit more research to allow you in. if louvre’s admissions are based on running background checks perhaps I’d go along with it :)
