Fun but has its issues
Like Self1er said, you spend too much time beating the shit out of Doug than actually serving customers. I would imagine that with the max level weapon he should be out in only a few hits, but the bastard takes like 8 hits regardless of the weapon. Another issue is the barrels on the fill screen are in a random order. It would be nice if they were in proper order so you could only fill barrels right next to the door. That would help immensely.
Also the music gets completely screwed up after day 15 or so, probably because of it speeding up too much. Fun game, but it does have issues that keep you from wanting to continue.
