My cousin worked at a payroll startup on Queen West back in 2019 and their office was an old Toronto Dominion branch. The teller counter was still there, this long marble thing, and they used it as a lunch bar. Problem was the vault. They turned it into a meeting room but the door weighed like 20 tons so they just left it open all the time. Felt weird having standups in a room built to keep cash safe. Old banks have those high ceilings too so sound bounced everywhere, you could hear every phone call.
