The real bad guys have other methods, which you can google (try "online financial crime").
I don't know what the success rate of that would be, but I'm pretty confident I'd come up with plenty of fodder for a 2 minute video in well under a day of sitting in a tent.
And that's just my first knee-jerk thought. A few practice runs before hand and I'm sure I'd find some other easy tricks to pull.
But it didn't have to be. What I said would work often enough. It really could be done on the fly, even if it wasn't.
The house information would be available at a land registry, or on a credit report. The alcohol information might be available through a brag "I just spent 400 dollars on Z", or through some kind of facebook-tie in "I like X bottles of Y". Or loyalty points.
Edit: D'oh! Changed "less" to "more"...
