I have to disagree with this statement. Part of the postmaster's role is to hear complaints from customers no? It's incumbent upon the OP to act appropriately and to state his complaint. Shying away from an adult, non-violent confrontation because you may appear threatening is how we devolve into regressive behaviors. Soooo many adults no longer know how to have interpersonal interaction with an adversary. In this instance, it appears the postmaster became an adversary, instead of an advocate for the customer.
