I almost started a thread about this. Balboa park in San Diego on baseball all star weekend. Three.....count THREE people sitting 20 ft from a table......not a cart.....where the signs werent even up (due to a light and wonderful breeze), and magazines were under an elastic band. I was in the area for an hour. Kids playing i the fountain.
Nobody even NOTICED then.....much less took anything.
There was an athiest booth down the way......it was jumpin.
