Don't get mad, get even...
A few years ago, right before Christmas, I met up with a mate of mine for a couple of pints. I had been out shopping and had a couple of bags with me. When I got up to leave I found that one of the bags had been nicked. Fortunately all it contained was a cake, nothing too valuable. I was told by the barman that a lot of stuff goes missing around that time of year because the scrotes know that people are likely to be buying presents and the like and pubs in particular get targeted. So, fast forward a year, I met my mate for a pint in the same place, and the same thing happened- the nice looking bag I'd brought with me got nicked. However this time it contained the massive output of my Labrador, scooped up in a Tupperware container and nicely gift wrapped.
