What is the appropriate action if a customer complains about undercooked food?

Offering to re-cook the item is the appropriate action when a customer complains about undercooked food. This response demonstrates attentiveness to the customer's concerns and a commitment to providing high-quality service. By re-cooking the dish, you are showing that you take the complaint seriously and are willing to correct the issue, thereby enhancing customer satisfaction and trust. This action also reflects professionalism and a desire to meet the customer's expectations, which is vital in the culinary industry.

In this scenario, addressing the issue through re-cooking allows the establishment to rectify the mistake instead of ignoring the customer's feedback, which would lead to a negative dining experience. Charging for an improperly cooked meal would further alienate the customer and potentially damage the reputation of the restaurant. Asking a customer to leave is also inappropriate and would likely cause further discontent and harm to the business's image.
