Bakery Door Trick/Glitch
If you don't have much time or you are not making food, or your ovens are full,
you can put something in front of your Bakery's door. For example, you can put the
cash register in front of the door. When the door is blocked, no people can get
in, so they wont give your bakery a bad star rating. This will let you level up
faster because you won't get bad ratings. When you can handle more people, put
your item back to it's place, and "re-open" to hungry people!
