Final answer:
The restaurant should discard the delayed food to ensure the safety of the customer.
Step-by-step explanation:
The restaurant should discard the food that was delayed and not serve it to the customer.
Perishable foods like hot food should be kept at or above 135°F until served. If the food delivery driver arrives at the customer's destination at 6 pm, which is 5 hours after picking up the food at 1 pm, the food would have spent too long at a temperature that allows rapid bacterial growth. According to food safety guidelines, perishable foods left at a temperature between 40°F and 140°F for more than 2 hours should be thrown out.
Therefore, to ensure the safety of the customer, the restaurant should discard the delayed food and arrange for a fresh delivery
