Holidays:why many british people?

I am scottish and live and work abroad and have noticed that the british nation are arrogant, noisy and seem to think they are better than the staff that serve them. how would they like to be treated the same in their workplace? i was brought up that if your nice to people they will be nice to you.. not so!!!
Answer
British abroad are cool in small groups once there is a plane load i think they must take scum pills to be able to find each other.
