A lot of industries operate in ways that they don't want us to know.

In fact, it is often the secrets that they rely on to turn a profit and keep their whole business model operating.

We never know what might be happening behind closed doors in pretty much every kind of industry that we may have interacted with, without working for them or having more intel.
