Not me this time, but a while ago I was *offered* a zone crossing to save me time whilst flying a microlight. As I crossed the extended centreline of a minor international (not MAN) an inbound BA international flight was vectored around me - seemed to bemuse the BA Captain slightly (judging by the tone of his voice as he read back the instruction), but we were both under Radar control, so ATCs call. Didn't actually inconvenience anybody, presumably just the easiest way to solve a minor problem.
