I was in my local charity shop last week and there was a young foreign guy buying something but trying to explain to the shop assistant he would like to bring it back if it didn't work. After he left she said loudly (shop full of people) that there were so many of 'them' nowadays and the country is a mess and no one speaks English. The younger woman working with her then chipped in that they shouldn't be allowed in if they couldn't speak English... I actually couldn't believe they were being so rude.
While I think it's important to learn the language of the country you live in I don't expect every foreigner to be fluent in English and think this woman was being rude and unreasonable.
