I don't know, maybe the "Army Of The Dead" character Bly Tanaka simply didn't want to divulge the combination because he reuses it for everything, but it certainly would have made their jobs easier if he'd given them that bit of info.

I wonder how the rest of this vulnerability disclosure story went. Was he locked up? Did future sewer workers just release information about secret tunnels into bank vaults to the general public? And if so, how did THAT turn out?

So apparently you can make a hotel out of an old bank (that must have been a heck of a bank!), and I suppose it makes sense that it's cheaper to find some way to re-use the vault than it would be to haul that thing out, so turning it into a meeting room is a pretty cool idea.

I don't know a lot about bank vault doors or how they're made, but those patterns in the metal make it seem quite ornate and I'm curious to know if they serve a function beyond looking pretty, since that's part of the door people probably won't see very often.
