Problems encountered after playing for a few days

The tea on the far right is refilled first. If the tea on the far right runs out while refilling the second cup, it will cancel the second cup and go to refill the tea on the far right. Modification: In the third row of the second image, there are two types of additives. If the customer wants different additives, you need to submit after placing the first additive, otherwise, the two will mix together.
