As a long time employee of a major home improvement chain this thread really does not suprise me.
Some of the things I have seen and heard are jaw dropping.
The 2 guys buying a hundred 4" x 4" timbers and 2 chain saws to build a retaining wall. While the 4 x 4's were loaded the one guy went next door to the liquor store and came back with 4 cases of beer and ice for the coolers so they wouldn't get thristy. We joked that the next time they came in their new nickname would be Stumpy.
Had 1 guy that wanted to know if he could take the guard off his die grinder and put a 71/2" saw blade in it instead of buying a circular saw.
Had a guy yesterday that wanted a couple hose clamps and a splice for the pressure hose on his 3500 psi pressure washer.
Oh well, "stupid is as stupid does".
