It disgusts me, but doesn't surprise me. When my hubby was buying a cd from a charity shop the lady behind the counter said she would have to get the cd to put in the case, she said they no longer pit them out on the shelves as people steal the cds and leave the case. We were dumbfounded that anyone could stoop so low. I no longer leave charity bags for doorstep collection as here too they have been taken by thieves collecting the bags left out for charity.
As for the guy who was stuck in the charity box, not only would I have left him there but I would have encouraged people to fill the box with rotting fruit and veg.
