Nail Him! is a manicure place structured as a two-stage process. Upon arrival, customers wait in a common area an average of 5 minutes before proceeding to the first available manicurist.
There is a total of eight manicurists. The average time for a manicure is 22 minutes regardless of the manicurist providing it.
Customers then proceed to pay, but they typically must wait in line an average of 2 minutes before they are able to do so since there is only one cashier who takes on average 3 minutes to process each payment.
