Your experience reflects my own. The people at some of the busier tourist spots in London (near Picadilly, for example) were pretty rude, but nothing like the jerks in France. I actually loved Paris -- the city -- but got away as soon as I could because of the people. Which is not completely fair because there WAS one shop girl who was an absolute vision ...
But Holland, Switzerland, and Germany were my favorites. Beautiful, clean, friendly ... England was a prize; it was history come to life for me.
