Managed a reprographics shop where our #1 vendor had a lock on repairmen. We had to pay $10,000 for the training fee, and I think we had to re-up on that occasionally. The tech's laptop had to have a key to login to the machines for diagnostics. He couldn't even manage most mechanical repairs because the software wouldn't allow it.

Océ is the asshole manufacturer, so you all know what not to buy.
