Customers arrive at a vehicle service centre and wait in the waiting area on a first come first basis. When their turn comes, the receptionist checks the car for any preexisting conditions. The vehicle is then checked at three work stations - suspension at station 1, motor at station 2, and brakes at station 3. Vehicles move between stations on a first in first out basis. After completing all checks, the vehicle returns to the waiting area until the customer pays the bill and both leave together.
