Final answer:
If a customer wants another side with their dinner entree, there may be an upcharge or surcharge.
Step-by-step explanation:
If a customer wants another side, other than fries, with their dinner entree, it is common for restaurants to charge an additional fee. This is often referred to as an upcharge or a surcharge. The amount of the upcharge may vary depending on the restaurant and the specific side dish requested. It is best to check with the restaurant directly to determine if there is an upcharge for additional sides and how much it would be.
