When times got tough in the automated inventory control business (pickers, stackers, label readers, etc.) the company at which I once worked decided to try its luck at revenue-collection systems for turnpikes and bridges.
We were told to get started on a turnpike toll collection system without a contract, as the fix was in; the new VP of sales's brother-in-law headed the turnpike commission.

So we built a prototype system complete with a ticket spitter that printed the Turnpike Authority name and logo to prevent fraud.

But the opposing party got wind of the graft and organized a surprise visit to inspect our operation. They could find nothing on the books to connect our prototype equipment to turnpike contracts. But near the end, one of them reached over and pushed the 'test' button, which caused the spitter to start spewing out tickets with incriminating imprints.

The marketers and execs ran around wildly, stomping on the tickets and collecting them, and substituting preprinted anonymous tickets, while the engineers snickered at the sight from outside the soundproof room.
Fortunately, no incriminating tickets got loose, and we got the contract and installed the equipment at ten times the usual margin. The VP then quit and moved to another company. Two years later our 'inadequate' system was again replaced at nearly four times the price by his new company. In fact, it was replaced every few years until the brother-in-law retired.
