Considerations to take as a UK citizen travelling in Europe? [closed]

The situation is far better than you are depicting it (or perhaps, how the UK media is depicting it). Despite popular belief, we haven't quite resorted to cannibalism, suspension of human rights and general carnage. It's kind of ironic you should mention this actually, since I've always perceived UK to be much more totalitarian and generally unsafe than pretty much the rest of Europe. You might find it hard to believe, but there aren't CCTVs on every corner in European cities, armed riots are very isolated activities, and police presence is much less than what you are used to in UK, particularly in London.

No there isn't really anything important to know about travelling around Europe. You will be fine.

A lot depends on where you go, how you go there, what you say etc., i.e. "Don't mention the war" ;). This isn't a UK/Germany thing, but when you go to any area that has a lot of strife just under the surface, everyone has to be careful. Remember that the UK is a rich, powerful country and has been involved in military campaigns all over the place. If you go to a pooer country and spout of about things, people could get offended. This is general travel advice.

If you are driving your UK car, people will be able to see the left hand drive, and know you're foreign, so might be a bit quicker to be annoyed, just relax and take it easy.

You may be mistaken for someone from USA.

There is also a lot of anger towards people in UK because we are doing better than Europe.

I wouldn't quite say this is true. Lots of people in various EU countries would not be envious of the UK, and would not think that the UK is doing better than other countries. Be careful of relying on British media (newspapers/tv/etc.) they tend to have a slightly biased view towards Europe. You are probably not getting the full story. (I once talked to a Briton who thought the UK takes EU law and goes above and beyond, France doesn't implement it at all, one look at the European Working Time Directive (etc.) will show you that the situation is reversed)
