If you see him you might do better to find out why he feels the need to steal rather than stump up a couple of quid. The answer might be very revealing.
The item was priced at £20, not a couple. And it is small enough to hide and scarper with. That's the answer.
And on top of that, he's a known druggie scumbag.
My country really wouldn't be any worse off if he was no longer of this earth.
If he comes in and tries to make off with the £300 Multiyork sofa, then I'd be impressed...
