every pilot should carry a emergancy falsh tash (i keep mine in my handy arm pocket) then in the event of sudden grief from some one be it another pilot or atc or atc wannabe then proudly affix your tash square up to the culprit dishing out the grief and say "what ho squiffy i dont like your jib! now be a good old chap fill the kettle to tabs and get a cuppa on" Any incoming threats should be replied to as "now thats just not cricket" and if it all goes tits up swift back hand slap and run like the clappers!
