How to be British in one sentence

I was watching "The Office" the other day, some kind of "Dilbert" type of show except it's pretty dramatic for a program aiming at deconstructing Good old corporate world.

Two colleagues are arguing and yet, and unlike us frogs, they manage not to insult each other. At some point one of them ends the argument :

"Let's agree to disagree".

Can anything be more British than this ?
