In my first couple of days in a new country I was out drinking with some English friends. There were some local people in the bar, and naturally we were keen to meet some of the locals and have a chat and maybe share a beer or two. We were quite lucky in that one of the guys in the groups was not only really fun and friendly, he also spoke quite good English ( well, I think the beer helped a little!). When we had finished it was decided we would go to another bar. So we all got on the train. The shocking thing was that this fun, friendly, English speaking business man suddenly told us not to speak English to him on the train. He was embarrassed that other people may hear him speaking English! Wow.
