We've lived in this house for quite a few years now, do Halloween every time. We do a mixture of opening the door and leaving a bowl in our decorated porch. Most of our neighbours do the same and there's never been any issues. Until this year.
After beig cleared out a couple of times pretty early in, I did some watching from the upstairs windows. And I've noticed gangs of teenagers (easily about 16) go through the street both knocking on doors and emptying any bowls they came across... Then running off and returning a few minutes later, trying to sweep through any refills 
There's realy no point to this thread other than me having a rant. As I've said above, this has never been an issue so it made me wander if anyone had a similar experience this year? Are teenagers these days really so bored/badly mannered to spend an evening doing this?
Us and next door took all our sweets in and only opened the door to genuine trick or treaters for the rest of the night. It would be a shame for the little ones to miss out (walking around in this hideous weather too) because others are so selfish.
