If you worked someplace handling money and saw a bill with perforated edges, you'd definitely consider it suspicious. That doesn't require someone to be stupid.

If my entire job was enforcing currency counterfeiting laws then I would probably have to be pretty stupid to think that perforated edges is a strong indicator of counterfeiting.

Why? Keep in mind that there are numerous people that have tried to pass off their pronted bills, Xeroxed bills, or bills clipped out of the newspaper.

Not only that, but why does having lower cognitive ability suddenly mean that others have free rein to mock you, make your workplace unpleasant, and so on? People are just trying to do their job and aren't necessarily educated on the intricacies of federal law on currency.

I mean, it's not just a 2,its a 2 you see him rip out of a book in front of you. If I had taken that at any of my retail jobs my boss would be on my ass, even if I knew it was legit. You think the casino owner really wants security making judgment calls about whether a dudes custom made book of perforated money is legal tender or not?

Is it really that stupid, in retrospect, that they investigated the guy that makes and uses a fake ID when flying? It shows he has a propensity to break the rules, and it may not always be in a strictly fun way
