How do the property managers not realize that someone has dropped off an ATM that isn't supposed to be there? Is it just me or does it seem like the properties are partially responsible if someone gets ripped off by this?
Organizations beyond a certain size are such that no single person can know everything that is going on. Where that threshold lies is a function of the general competence with which the organization is managed. To get a sense of the level of competence of the Las Vegas Riviera, consider this anecdote:
They're probably just as naive as I was (before reading the article) about the existence of fake ATMs set up by scammers. I don't think it's common knowledge that this happens, is it?
If someone set up a Coke machine that stole people's dollars, do you think they'd notice? This doesn't have anything to do with the scam, but simply being completely oblivious as to what's going on in your place of business.
I don't think the people at the front desk are aware of which contracts for vending machines or ATMs. They could have had 4 guys bring it in and make up a slick story about how they had a work order to install the machine and the front desk would probably not have the authority to act in any direction other than send the info up the chain.
