When I’m doing Radar it most certainly is my zone Matey. If I clear you in, it is on my licence, and, given the litigious world we live in, if you cock up my head may well be on the block. If you sound or act like a clown you ain’t getting in on my watch.
Nice attitude - unfortunately if a pilot is already flying in the zone and controllers change over and one sounds or acts like a clown, he doesn't have the luxury of refusing your service, whether he be IFR, VFR, commercial or otherwise.
