Ghrrrrrrr, Spanish! I was in Auschwitz last year and went back to Krakow by bus, full of people of all nationalities, Jewish, French, Polish, some Brits, and a handful of Spanish.
Understandably, everyone was sad, subdued, and emotionally exhausted, leaving a place such as this. Except not for the fucking Spaniards, who occupied the end of the bus and proceeded to yammer on top of their voices about some bullshit or the other, interspersed with loud cackling and shrieking. FFS. Me and a couple of other people eventually told them to SHUT THE FUCK UP, and we weren't polite about it, although no hand waving was involved.
And that's far, far from the only time I encountered rude, obnoxious, and extremely LOUD Spaniards on my travels. It's their 'fiery temperament', apparently. So I don't blame the man on the train, xenophobic or not. That woman was a twat.
