>We had one client who pretty creatively fought the system. Reputedly mobbed up. They set up trailers in the parking lot as "slot locations" and parked bogus inventory there. But they got caught.

OTOH that's exactly what I recommended, for a different purpose. They wanted to know the results of classing the eggs, so I told them to invent a virtual location called "classing", move unclassed eggs into it, then move out classed eggs (which were about five different SKUs). The number of eggs should fit, the difference in value should tell whether the quality was above or below average.

The idea didn't quite take, not immediately. It did gloriously, two weeks later, when their boss came to me with that scheme, presenting it as his own idea. I could only congratulate his ingeniousness... because 1) I didn't have to do anything, 2) if I didn't, I'd have to invent something else.
