Effective at the next reboot, to help people to avoid accidental retirement due
to typos, innkeepers now prompt you to type 'rent retire' one more time after
the first request.

So please do not cut link immediately after typing 'rent retire' once unless
you want to stay unretired and pay linkless rent.
