QuickBite" is a popular fast$-$food restaurant located in a bustling urban area. The restaurant has experienced significant growth in customer traffic, particularly during lunch and dinner hours. While the restaurant is known for its delicious food and cleanliness, customer complaints about long wait times have been increasing. These wait times occur both at the order counter and the pick$-$up area, leading to customer dissatisfaction and a potential loss of business to competitors.

The restaurant management has decided to apply queuing theory to analyze and address the issue of long wait times. They have collected data on customer arrival rates, service times, and the number of service stations $($counters$)$ during different times of the day.
