Well stocked indeed but there is something obvious missing.
Where is the bartender? Where are the guests? There is a simple answer to odd state of affairs. It's the end of a big night out and we have out drunk all the patrons who have left. The bartender has finished for the night and asked us to leave when we are ready by the side door entrusting us to lock it behind us.
