I'm sure this wasn't cheap.
The ironic placement of this advert shows a bench designed to dissuade homeless from being so crass as to lie down in public.
New benches are being installed with bars across them to prevent sleep.
Because apparently letting the homeless sleep or lie down like this is unacceptable.
Elaborate fencing surrounds the base of most over passes and bridges suitable as shelter.
Eventually the homeless just stop and sleep where they lie.
Eventually the homeless problem will be so great that sweeping it under the rug will no longer be possible.
