I really like alternative solutions like this to bad behaviour. My favourite instance of this is story of hooded teenagers outside stores intimidating passers by and general unwanted loitering in car parks etc. The solution was to loudly play music that the miscreants would really hate, like Engelbert Humperdinck, Neil Diamond, Dolly Parton etc. They moved on pretty quickly because they couldnt stand listening to it.
