What is one way to increase fry sales?

Asking customers if they would like fries is an effective strategy to increase fry sales because it engages customers directly and prompts them to consider adding fries to their order. This approach can lead to increased sales as it creates an opportunity for customers to think about how fries complement their meal. Additionally, many consumers may not think to order fries unless prompted, so this method can effectively boost sales organically.

Providing options and reminders can encourage upselling and enhance the overall dining experience, potentially leading to higher satisfaction and return visits. The other strategies listed would likely limit customer choices and reduce impulse purchases, which can negatively affect fry sales.
