My mate works with foreign language students in Manchester and says EXACTLY the same thing about the Chinese- very difficult to get on with and overall pretty dull.
The problem is we as a nation love to travel/holiday, i'd argue more than any other nation in the world... and you can also go abroad very cheaply thesedays. That coupled with our drinking culture = thousands of completely uncultured groups of lads etc trotting off to various hotspots around...
