How can I fill up all the fridges and vending machines?? Everytime when the worker get the supplies he just stand there doing nothing! And it says that he's occupied and has the food/drinks/cleaning supplies. That's why all of my customers are leaving.. Am I doing something wrong or did I miss something?
Are the storage places accessible? If they take the full box it means that they are going to bring that box to the storage places. If between the storage places are some walls, try to delete some of them to make a way to let the workers go directly to the storage places (sometimes doors get bugged and don't let the workers move).
If it still doesn't work, it would be great if you send us a screenshot of your game.
