Ahh yes,
the good old apprentice tricks.
A mate of mine was sent to the supply house by my Boss at the time to get 15 Left-hand Elbows and was told that there had better not be any Right-hand ones in the box or his pay would be docked.
Another one (Same guy) was bi-directional cable.
The young fella was told to tell the supply house not to give the Boss any more of that uni-directional cable.
(Same stuff, like Romex 12-3).
That Uni-directional stuff will burn someones house down one of these days, AC has to go both ways you know!. [Linked Image]
