Wait.

You decide to wait if the landlord will wake up soon and as you stand your sandals begin to wrench your feet to the point when circulation would stop. You sit down to rest on the bench in front of the landlord's desk. You wait until an hour passes. Then another hour passes. Then another.

Then you find yourself that you have slept sitting down and it is morning. The landlord is gone. You remember that you have a package that needs delivering and you cursed under your breath.
