We've never had a problem with Shoup's.  However we came up with a phrase when I worked off farm that explains it:

Screw ups begat screw ups
 
I don't know why but when we had one mistake it just started snowballing until we finally got it fixed.  Sounds like you're experiencing one of those.

Oh and for the idiots giving you a hard time about working off the farm, let me suggest they try it a couple years. With no employees doing it all yourself or with Dad.  It gives you a whole lot more respect for the guys who have to do it.
