Flying suit is for flying in, it's not a difficult concept.
Desk flyers know your place when working in Bluntyland/Handbrake House, it's not a difficult concept either.
You are also smelly after you have been flying, so please don't wear them unless you are doing/about to do that flying thing or can manage an 'aircrew shower' before venturing out into Bluntyland.
It put us off our donuts and coffee over in the Tower!
