I thought it was called a Safe Deposit Box.....cuz it’s a box inside a safe/vault....
Sirkit, you’ve hit upon one of my pet peeves. YES!!!!!! It is a SAFE deposit box because it is safely deposited in the vault. “Safety deposit “ is one of the biggest misnomers out there, but it is said all the time. Your post is so precious I’m going to print it out and store it in the wall safety here in my office
