Which of the following is NOT part of Five Guys' operating procedure?

The choice regarding free refills for customers is not part of Five Guys' operating procedures. Five Guys is known for its focus on quality and a specific customer experience, which includes serving freshly cooked food made to order. While many fast-food restaurants offer complimentary drink refills, Five Guys differentiates itself by ensuring that the customer receives a freshly prepared product rather than a self-serve beverage system.

Frequent cleaning of workspaces is crucial for maintaining hygiene and safety in any food establishment, and Five Guys emphasizes cleanliness in its operational standards. Rigorous burger cooking standards reflect the brand's commitment to quality, ensuring that each burger is cooked to perfection for the best dining experience. Pre-cooking fries to a set standard is also a part of their operational procedures, ensuring consistency and quality in the product served to customers. Thus, the emphasis on these operational standards highlights Five Guys' focus on food quality and customer satisfaction versus providing free refills.
