I worked in a small town (900) when my wife & I were held hostage. Big town, small town when it's a whacko it's a whacko.
Security training for myself & wife (ex-banker) and my secretary paid off. Calm voice, calm face, nothing to get excited about. He left us tied up to go to the drop site where the sheriff waited.
Whacko specifically wanted $30,000 ransom which was the same amount as his loan request I had denied. Yeah, yeah my boss also said something about how much I was worth. The next bank I worked for knew about this and wanted me to be security officer. I lasted about 6 months and had scared the stuffing out of too many people.
The point is I would encourage very limited use of teller or even platform last names. Never keep family photos in public, etc. The less information the whacko has to work with the better.
