We have all been there, where Zach was when he wrote this note for the UPS delivery guy. Having a bad handover is enough to leave you wondering if you will ever receive the things you ordered earlier. Because there is no guarantee you will be able to get to the door when someone knocks.
It seems like it wasn’t the first time for this guy since he made preparations for his future knocked-out phase. He requested a heavy task from the UPS driver, of banging on his door like a maniac, to make sure he doesn’t miss his delivery.
