A sign for "forbiding to sleep"

My friend Hana-chan came from Fukui prefecture and we met at the Asakusa. We had yummy Monja-yaki (a kind of pancake in Tokyo) and beer.

Later, we walked around Asakusa and I was shocked to find this sign...the original sign underneath says, "forbiding to leave your bike here," but the 2nd sign on the top says, "forbiding to sleep here"...yes, it is the sign for bums who sleep on street...
