Hostel

Bring your ID,and tell where you come from.Yes, there is room for you. Always.
Here you can find almost everything you need.
Look, feel free to take whatever you want.
You stay for a while. Enjoy yourself.
Then you pick up your stuff and go away.
If you are around someday, stop by maybe.

Well, that is basically it:
You arrive when you want, stay as much as you want, and leave whenever you want.
Come back if you want.
This way, it feels good for everyone.
Except it doesn't.
