Why is he crying???

The other day, soon to be ex let a neighbour throw some stuff in the skip. Among the items was a portable barbeque.

This afternoon, he comes in and he's complaining because the barbeque is gone and there's now a mop in the skip that hasn't come from ours.

I don't see what the problem is... he wasn't planning to keep the barbeque - and, in comparison... the mop takes up less space than the barbecue did, so I have the space to cram a few more items in there.
