I mean I really doubt that someone who handles European eccentricities for months all by themselves is gonna get nervous about that question.

At the very least, they may had mishaps with the locals did to the language barrier, got scammed a few times, learned about eating healthy good food for once in their lives, got to see and listen to the many guided attraction tours, maybe knew a few nice people here and there for future reference, got to experience a city full of trash thanks to union actions and so on

All in all, a good learning experience
