I'm with Comp on this one, bloody scuffers!!
Heard about the scuffer on a Scottish camp who set off with his new gun. First person he pulls is one of the Gnd Radio SNCOs.
Scuffer: "You know how fast you were going?"
SNCO: " No do you?"
Scuffer: "Well Sarge my new radar gun here tells me you were doing 15mph above the airfield limit"
SNCO:"New Radar gun eh? Had that checked out for interference on Navaids around the airfield Cpl?
Scuffer:"No Sarge just got it"
SNCO:"Good hand it over then I'll get it done for you"
Scuffer:" Oh thanks"
SNCO then put gun in bottom drawer for a few weeks until OC Plod begged for it back!!!
