I once saw a news article with interviews of anonymous bunker tenders; essentially, there is a small industry of former special ops folks that are paid to live in the bunker and maintain it.

The main point they made during the interviews: If things ever get bad enough for the owner to want to move into the bunker, the #1 priority of the guards will be to neutralize the owner. They worked out detailed contingency plans while twiddling there thumbs and rotating cans of caviar.

It turns out you cannot eat electronic money that’s sitting in the middle of a bank’s bombed out business continuity vault.
