Penford, Uitenhage Manager and staff need training

I visited Mr Price Penford in Uitenhage today to return an item of clothing. I showed it to the security guard at the entrance and he inspected a bag I had with a cooldrink in it. He was satisfied with it and I proceeded to the queue in order to return the item only to be shouted at by the manager and cashier to leave my "parcel" at the till. I didn't see the point as I was standing in the queue and not wondering around the store. I refused and left feeling irritated at the lack of discretion and common sense from the management and staff. This is the second time I've left the store due to poor customer service. I would advise that you provide Penford, Uitenhage staff with additional training on basic etiquette when dealing with customers.
