I found a loaded 9mm Uzi Automatic Pistol in the glovebox of an old 500SEL many moons ago when I was looking to find something with the customers phone number on as Carol had forgotten to get it when the Car was dropped off !! ...................
Guy was in a right panic, came in all flustered "errrrrrr I left summink in the glovebox Dave", as he looked up at his Car on the 4 post lift !!
Without saying a word I ushered him into my office and opened the safe, let him take it out, as I'd put it in there with gloves on !!
Got a nice cash bonus when I gave him the bill for the Trans Rebuild

He was just one of those "sarf Lundun" fellas, (back in the late 80's)
