It would be nice if the night time greeting was different than the daytime greeting. Something along the lines of We are closed. Come back in X hours.
If you really wanted to get fancy, within two hours of closing, Oh we just got everything put away. Come back in X hours and we will help you then.
Within two hours of opening, Hey, we are just getting everything out. Give us X hours and we will be ready for you.
