Sauce

Sauces can be added to a customer's order when their emotions are showing as Happy, Peaceful, Bored, Sad, or Angry. Players can differentiate between the five emotions by the background color of a customer's speech bubble, which is white by default.

While it is possible to guess a customer's current feeling by the emotion displayed on their face, this method does not always work with every character. The best way to correctly guess what a customer is feeling is by taking note of the background color of their speech bubble.
