Only if you think of the other person as lesser than you or you are fearful of the interaction.
Traveling abroad and being a tourist, usually invites tons of conversation and sharing of culture from both sides, especially if the person visiting has put in effort to learn the language.
But why do you desire to communicate with literally everyone in a big city? I don't care about that.
The reason I live in a big city is that it has enough of a base to make even small fringey communities viable. Such as the makerspace I'm part of, and some more NSFW activities too. I'm sure 95% of people don't care about those things but for me they are very defining.
I'm just being descriptive here, not normative.
