The barbershop gets 30 customers/day of each type and each customer served (irrespective of

type) provides $20 in profit contribution. Also, there are 3 staff members at the Shave station and

3 staff members at the Haircut Station. The rest of the stations have a single staff member each.

The barbershop operates for 8 hours every day. What is the bottleneck in the process? Suppose,

the number of staff members at the Shave station is reduced to 2. What is the loss in profit

contribution per day?
