I'm always confused by glider pilots who turn up to the club in nomex gro bags.., protection against cigarette burns maybe?
One thing that does strike me as amusing is flying into an air display, Old Warden, Duxford etc in my usual garb of jeans and tatty leather jacket (so tatty I've had to bin it and buy a new one which is embarrassingly shiny as yet being as I'm still grounded) and seeing the spotters in flying jackets covered in badges.
