True or False: Customers can mix candy flavors in slushes.

The statement that customers can mix candy flavors in slushes is incorrect, making the answer false. In many establishments, slushes are typically prepared with specific flavor profiles, and the mixing of candy flavors may not be an option offered to customers. It's common practice for beverage vendors to maintain the original integrity of the slush flavors for consistency and quality control.

Additionally, while some places may offer customizable options for beverages, the mixing of candy flavors might be restricted based on their menu design or preparation methods. This is done to ensure that customers receive the intended taste experience that each slush flavor is meant to deliver. Therefore, the concept that mixing candy flavors is allowed does not apply universally, reinforcing the correctness of the answer.
