My hangar, one man band, was working away never saw him straight off, by that time he was already lifting items off the bench.. was a WTF moment.
Believe me when you get people walk in and start going through your tool kit looking for a screwdriver to do XYZ up you soon start to get peeved to the ignorance of some people, these are my own tools and probably are in the £15,000 plus range, a ratchet screwdriver costs about £60 to replace the last time i looked, top that off with the fact you then have to start tearing aircraft apart because you cannot find it.... so yes one can get a bit short with them. And before you start on about shadow boards etc, believe me the best tool control is to have to buy them yourself, i can look in my tool kits and instantly see when something is missing, everything has it's set place.
