Funny thing headsets
Funny thing eh? The company would not dream of asking you to share a oair of shoes - say each ops rooms had several pairs of each size 6 through 11 for either Captains (nice shiny newish shoes) and F/O's (second hand slightly scuffed oldish shoes) and some nice little shine 'tap shoes' for the undecideds and girlie pilots. Well, pretty stupid eh? Yes! But they are quite happy to try and make people share the hair, dandruff, earwax, spit, scrambled egg from breakfast etc etc.
Geeeze the bean counters have some explaining to do! Even in the military each pilot and/or crew member is issued his own helmet and flight suit(s).
