Yes, the scam about recruiting fire instructors is like this: train fire instructors and then cut leeks. The next routine is to let you apply for a certificate. Fire fighting needs to be qualified, not capable if you want to do it. Does this qualification cost money? In fact, it's useless for you to spend money, either dismiss or fail. Let me give you an example. Same routine as the wine tray. This job is to get rid of it, so that you can spend money on qualifications or research and training.
