I am not proud of how Spaniards just don't pay public transport. Whenever you don't have to show your ticket to the bus driver, nor to use it to enter subway, they just don't pay. So, they are always targeted by keepers when they hear them, sure they won't have paid, so you can see big groups of Spaniards fined in Berlin subway and places like that.

This is a more unusual behavoir, I'd say. The typical way is not respecting the rules in poorer countries, as Swiss drivers speeding in Spain or many travellers feeling proud about briving or being arrested for stupidities in developing countries, things they would never attempt in their own countries or neighbouring countries.

Regarding Brits' behaviour, years ago the British honorary consul in Ibiza resigned arguing he felt embarrassed about his countrymen behaviour. We Spaniards all thought that yes, it could be embarrassing, but he was obviously in the wrong place if looking for peace and tranquility. Arturo Pérez-Reverte, the most successful writer in Spain, wrote an article which did not actually criticize the British tourists -not praised them either-, but our general approach to these matters, saying that "there is nowhere like Spain to vomit in the streets". Not only British/French/German tourists used to do it, WE ALL have done it, we all have pissed in the streets while drunk. We Spaniards are just like that. Our own attitude fostered this behaviour from tourists, so we should not blame them for doing it massively.
