Best customers drive straight into the workshop.
Even better customers drive straight in and beep their horn to notify you of their presence.
Even more better

customers drive half into the workshop and stop right inline with the buzzer and look around pretending that they dont know they are setting the buzzer off.
The ultimate customers tell you how to fix their car and that it will only take 2 minutes " its just a loose wire"
The joy to be had when seeing their faces when you give them the invoice.
Can you tell I dislike many customers with a passion.
Thank God I dont deal with any nowdays 7 - 4.
