That's mainly because the attitude towards drinking beer there is different. Europeans favour the use of smaller glasses, replenished more frequently, in order to keep beer cool,
rather than having a pint of beer sitting around for longer getting warm
However, if you drink pints of beer quickly enough, I guess that isn't a problem!
I like it abroad when specific beers have their own matching glasses. This is especially prevalent in Belgium, where you get 'beer lists' in pubs and restaurants, rather like one gets wine lists here. Class!
My bugbear in the UK is pints of lager being filled right up to the rim of the glass, allowing no room for a head... That almost never happens in Europe, where an inch or so is allowed at the top of the glass for a nice frothy head, which is how lager or beer should be served... I want to have a nice 'beer moustache' after I take my first sip!!
