Safe Deposit Box
  
"Safe." Well, you hope it is, anyway. But it seems like, in every Hollywood movie, there's a set of criminals who break into the bank safe and, like...take everything.
So is it really "safe"? Ever see Marathon Man? Maybe not so safe.
Anyway, banks charge a bit for usage of a safe. Some give it away for a year for new clients as a kind of marketing spiff. Regardless, they're there. You see 'em behind thick glass and bars. And they're supposed to convey that this bank is...yes. Safe.
