OK Americans, I don't want to worry you but you appear to have lost your title as the rudest, loudest, most obnoxious tourists on the planet.
Let me explain; I was recently in Paris and as usual there were a lot of American tourists about but mostly they were reasonable and sensible. I say mostly because there is always going to be a few rude, loud people about.
However, it now appears there is a new kid on the block. Take a bow the Asians - I mean Chinese, Japanese etc. These tourists have no understanding of the meaning of the word queue and will push on to busses, or into lines with no thought that other people were there first. They will even do it when they do not even have the correct tickets (or even any tickets at all). They are loud - they shout at each other. They dress very inappropriately and the get in everyone's way with their cameras.
So America, time to up your game (lower your standards?) and get back to being rude and obnoxious.
Before anyone questions me, yes I am aware of the UK's standing - we are the best tourists in the world and are a pleasure to be around and I won't listen to anyone who says differently.
