Every nation, tribe or culture has an inbuilt sense of superiority, it is a large part of what makes them.
I agree that watching UK tourist, especially the elderly, abroad can be embarrassing, so I mainly avoid touristy type places.
And the opposite is that if you make the effort you will be very popular.
Not so much as popular, as an easy transition from stress in trying to make yourself understood, to an easy relaxed atmosphere, and a helpful waiter-barman-sales assistant, who smiles, and is more readily disposed to your needs. It also shows a modicum of respect to the host country, as opposed to the ignorant louts who insist being "British" wherever they may be. Not only the British, I saw this time and time again, especially the Americans, not all, just it seems those in uniform, in large groups. I witnessed this in Bern, bawling and shouting, and generally making themselves seem obnoxious and loud. At the airport terminal in Bergen, a crowd of British civvies who were drunk, and generally playing up, made us all angry, and ashamed to be British. We said nothing. I picked up a few pertinent words and phrases in Norway, which helped smooth the path of inter country relations, especially in the shops and bars, and if nothing else, it expands your worldly knowledge.
