Heathrow, interesting that you mentioned you worked for ATC, any reason why you cant coordinate with Mastrict sic for for higher or is that below your assumed dignity?; and you prefer us to meander over the English Channel to be someone else's responsibility?
You clearly are spoiling for a fight, so not sure why I bother to reply.
But in the unlikely event you do actually fly an aircraft in/out of LHR, rather than just sit down the back, maybe next time you could check who you are talking to prior handover to Maastricht. I think you'll find you left LHR's freq's sometime back
