The manager thinks that students will go elsewhere for lunch if they have to wait more than 5 minutes. Therefore he's thinking of hiring another server to help Lenny, reducing the customer service time to 4 minutes

How long will students wait in line if Lenny gets help? Lenny, a graduate research assistant "moonlights" at the short order counter in the student union snack bar in the evenings.
