You have some sympathy. We bought a new set of fire proof overalls specifically for re-fuelling for last year's Classic TT/ Manx, (£235?), and my mechanic was at this year's TT with them and they were no good, so I need a full set too!
Absolutely barmy, especially when there's bare fleshed ladies swanning around the warm up paddock when all the bikes are assembled together with hot engines and full of fuel.
At least  when the riders are re-fuelling, the whole entry isn't there.
