Yeah but here's the thing,when they boo you in other venues,regardless of who you are,they do it for a good reason. Djokovic got booed in USO because of his comments against Roddick.

In RG for example they boo you for checking freaking ball marks. The one surface where you can see for yourself where he ball went and the parisians seem to have a problem with that. They even booed former crowd darling justine henin when she went to check a ball mark. The thing is,in any other big venue,they crowd won't be against you unless you are playing a local player or you have done something to offend them. In Paris they decide that they don't like you and that's it. You simply cannot make amends with these people unlike with crowds elsewhere.
