Trust me, I never did it :) I agree with your statement, but I also think there should be either police (guardia urbana?) taking care of drunk tourists, or just close hotels and don't invite tourists. Otherwise it looks like one part of citizens is happy to take tourists money, and other just hate them - not fair to tourists.

And I need to mention I've never seen disrespectful or hateful locals in Barcelona - almost every local citizen I met was kind and polite, even if our talk was possible only with Google Translate.
