Post Office Bureaux de poste pour produits et services

I was recently in the sliver springs Canada post office at the shoppers. The manager Peter was very rude and arragent.I am seriously disappointed in his customer service and his ability to be manager at this location. I frequent this location often to revive the mail and this was by far the worst experience I've had. He also told a women trying to by stamps that since she was so impatient she could by stamps at the front.
