How do I stop my Popularity going down when I am not using the game?

If you are worried about your Popularity decreasing while you are not using the game, you can use the ‘Redecorate’ button to remove any doors on your restaurant while you are not using it. This will stop customers coming in and getting upset if you are resting your employees, or your employees need food or rest. You can also put a table, plant, etc. in front of your door(s) to stop customers coming in.
