If they take something it is because they really want it.
I am not sure I can believe that. I've done community events where we hand out free trinkets and people have physically pushed each other out of the way just to get some $.05 piece of plastic crap. We had to stop leaving stacks of stuff on the counters because people would walk by and sweep the entire lot into their purses. Once I was handing out pink rubber bracelets and an elderly man swept a bunch of them into a tote bag--I asked him what he planned on doing with them and he said, "Nothing, I just want them 'cause they're free."
