drain unblocking vans are always brightly coloured. but why ? i went down and knocked on the window of this van and asked the chap inside.

unfortunately he was incomprehensible but i think he said "it's management's idea. our senior management are women aren't they ?" i said i didn't know and left it at that.

possibly it's something of a backlash against their engineers being constantly covered in brown yuckyness ?
