Soon a customer arrives with a car for repair. The fault is obscure but the defective part is identified. Suppliers are contacted and reckon it will take 3-4 weeks for the part to arrive. Customer accepts this especially as a courtesy car has been made available.
Everyones happy.
At the end of the first week, the parts arrive, the garage man is overjoyed as he can reunite the customer with the car far sooner than was expected.
The repair was carried out and the customer advised their car was ready.
Customer arrives and the bill is passed to the customer.
The customer accepts the bill is fair and as agreed at the outset, but then announces they want a discount of mega dosh because the customer had fuelled the courtesy car and then commenced a rant that, in short, the car was ready too soon.
Finale, courtesy car facility withdrawn at garage.
