The inexorable march of the high vis jacket

[Nick]

and the yellow helmet of course 

A chap has just come round to check on some workmen who are repairing a wall adjacent to the car park here. It is a very low wall so the workmen are KNEELING DOWN to fix it. SO why the fook did chappy have to return to his car to fetch a yellow jacket and a hard hat????   

Growler told me a while back about some numpty at a Red Arrows show. Mr G asked why he was thus attired. "In case one of those crashes, " said the numpty, gesturing at the sky.
