What is required for someone wanting to utilize the BOGO deal?

To utilize the BOGO (Buy One Get One) deal at Denny's, customers must purchase a beverage. This requirement is in place to encourage drink sales alongside meal purchases. Beverages often have a higher profit margin, and tying them to a food promotion helps Denny's maximize overall sales.

The other options do not fulfill the criteria for the BOGO deal. For instance, simply requiring nothing or ordering two meals without a beverage does not align with the promotional structure designed for the offer, ensuring that customers engage more fully with the menu by purchasing beverages. Additionally, the requirement to register online does not apply to this specific promotion, making it essential to understand that a beverage purchase is a key component for the deal.
