DRM Bikes received an order for a customized bike.

DRM Bikes received an order for a customized bike. Bret, the employee in charge of ordering parts for the custom bikes, ordered two fewer clamping bolts and realized the mistake only after his co-worker Julio complained of a shortage in clamping bolts. Julio suggested that it was best to inform the customer about the situation and place a new order for a set of bolts. Martino, Bret's co-worker, suggested using an old pair of bolts because the average customer wouldn't recognize the difference. However, Bret knows that the customer is an experienced biker who will notice the difference, and hence suggested that they use the old pair on a bike for a customer who would not. Considering the evidence presented, what is the ethical step for the sales manager to take?
