During the Coronavirus pandemic, the restaurant is only open for drive-through and wants to provide quick service to their customers to minimize the risk of exposure. They currently have assigned one lane to serve the drive-through crowd. Bobby recognizes that having a lengthy line is likely to deter other customers from arriving at the restaurant. Now, Bobby needs to figure out if he needs to open a second drive-through lane or not. He spends a couple of days to observe the patterns of arrival for customers and notes how long it takes for service to be provided to each customer from the time they enter the drive-through lane until they leave. He finds that the average time between the arrivals of customers is about 3 minutes with a give and take of about 45 seconds (0.75 minutes). He also notices that the average service time is about a minute per customer with a give and take of about 20 seconds (0.33 minute). He estimates the hourly cost of having a queue would be about $15 per customer lost and his cost of opening a new lane would be about $20 per hour. Should Bobby open up another lane? Does he need another lane, or can his restaurant sustain as is? What would you recommend he should do? Show explanation through excel.
