Anacdote, I have a friend who is a locksmith. I needed his services one day, gave him a call, and it turned out his day job had evolved since I last talked to him 5 years ago.

Basically, he was now just a safe cracker. He is a a locksmith, but 100% of his full time hours are cracking safes. He didn’t even carry around the stuff in his van to repin a lock. He gave me mates rates but the shop had to do it.

This man was attending multiple callouts, per day, to crack into a safe. Because of, you guessed it, human fallibility.

In a city with with millions of people, basically a hundreds of people needed a single locksmiths service because they had locked themselves out of there own “personal store of wealth”.

I’ve heard zero such examples through traditional banking, with the exception of stolen cards.
