Where I live is a rough party zone for upper-chavs who want to get smashed on the cheap. You should see the pile of trash they live behind.
There's a group of Polish homeless who turn up on Sunday morning and clean up all the cans and bottles to drink the left overs. Then they put the cans and the bottles in the rubbish bins! They do what the council should do.
The homeless (at least the ones who choose to be) fulfil a useful social function.
