What should Sonic employees avoid touching when serving guests?

Sonic employees should avoid touching items that will come into direct contact with a guest's mouth, such as utensils, straws, or certain food items. This practice is crucial for maintaining hygiene and ensuring food safety. By minimizing direct contact with items that a guest will use to eat or drink, employees help prevent the transfer of germs or contaminants, thereby protecting both themselves and the customer.

While other options highlight valid considerations in a service context—like the need to be cautious with anything that could potentially fall or the importance of handling station equipment properly—the primary focus here is on direct interaction with food and drink items that could enter a guest's mouth. Adhering to this standard is essential in the food service industry for upholding health regulations and providing a safe dining experience for guests.
