I often can afford to give the money away, but there is a strong difference between feeling like I helped someone in need and feeling like I've been conned. If an obviously homeless person came up to me, giving them aid would be one thing. When an obviously clean and healthy man walks up to me with a story about being a college student, wearing his college ID around his neck (which is odd and I believe is used to create some false credibility to a sob story), I feel like I'm being hassled and shaken down.

And I can't believe that anyone would just heist the coffee machine. Have you thought of having a security camera put in the lobby??
