Final answer:
The journalist's claim about restaurant waiting times is unfair because it does not consider the multiple factors that can affect waiting times at a restaurant.
Step-by-step explanation:
The journalist's claim about restaurant waiting times is unfair because it does not take into account the various factors that can affect the average time it takes for a restaurant to serve food to its customers. There are several variables that can influence waiting times, such as the number of customers, the complexity of orders, the efficiency of the restaurant staff, and external factors like peak hours or unforeseen circumstances. A single average waiting time does not accurately represent the entire range of experiences that customers may have.
