I've been to 15 countries in the past five years, and the way locals treat tourists varies wildly. In Japan, I felt like a guest; in Barcelona, I saw graffiti telling tourists to go home. Is it fair to ask travelers to adapt to local customs, or should destinations change to accommodate the influx? I'm torn because tourism brings money but also strains resources. What's your take—should we prioritize the visitor experience or the residents' quality of life?
