I am in full agreement with the above, but I do have to admint, partaking in the odd FEB once or twice on holiday. Not because it is English, but maybe because it was substantial with a long day ahead.
As for the rest mentioned, and in particular by Pavlo, how embarrassing. I have often been embarrassed to be British when abroad, because of the way people from the UK react to the least little thing. And as did Pavlo, just stand back and let it happen.
One of my real pet hates is the same as Nigel's. People standing up as soon as the plane stops, scrambling for baggage. I have been known to shout down the aircraft, "Sit Down", because the Cabin crew cannot be heard. I have obviously had some looks, and some threats. But what is the rush, the coaches will not leave until they have all names ticked off.
Relax, take it easy, enjoy it. Eat and drink locally.
PS: It is highly unlikely that one would get todays fresh loaf of bread from the UK, in time for breakfast, either in Spain or Greece.
