Let's start a thread about this again. What's something that 'everyone knows' in your field, but that would probably shock the general public if they learned about it? 
I'll start: every 'magical' and 'innovative' service from a tech company that works better than you would expect from a computer, only does so because there's a lot of unnamed people behind the scenes papering over all the broken stuff and manually fixing things. The company just isn't telling you that.
@joepie91 Most car chargers you can use a paperclip to bypass payment on, by shorting either the 5v rail or the 12v rail that controls the relay, and usually don't have security alarms on the way to access that relay.
Yes, you have to access it destructively. Yes, it's probably not safe. But it's there.

AGI, actually stands for A Guy Instead (of a computer).
