Did that actually happen to you? Only, it’s been doing the rounds on the Internet since before the web existed.
Sadly this actually happened, I know the site and person who called us – some of our customers are a bit thick. We often get calls to the on-call helpline in the middle of the night because they can’t find any paper for the printer – like we should know where they store their paper, never mind the fact we probably didn’t even provide the printer.
I’d be very tempted to kick it back to your boss going “you have two options, you can get me read-only access to the relevant part of the DB from the suppliers, or you can put up with it looking crap.”
Getting the password isn’t going to happen. If it looks crap, then so be it, I’m just trying to make it look a bit better with the tools I have/can find.
