The same in EU - e.g. in Italy, if you want to see a church from the inside, tourists pay a lot while the locals don't.

Your examples are more like colleges charging more tuition on out-of-state student, or tourist attractions charge lower price to locals, which are made public information. The context under this thread is talking about dual price that is deliberately taking advantage of information asymmetry, differentiation, or even discrimination based on social class and skin color.
