Rude, Rude, Rude!

My husband & I visited PNP Gwood on Thursday. We purchased a items & wanted to pay with the RCS card.New procedure we did not know of is that authorization now needs to be obtained.The supervisor Regina gets called to get an auth. We held up the whole Q. After several minutes my husband walks to the office to find her. She then answers by shouting at my husband that she is busy with it. So she gets to the till and basically throws the card down,mutters something under her breathe & walks away. So the cashier swipes the card and the goods are paid. WE DIDN'T GET OUR ITEMS FREE, WE ACTUALLY PAY FOR GOODS! I have no words anymore when it comes to customer service, cause lately I feel that customer service was last practiced maybe like 15 years ago, today it's just a word used or someone with no manners, etiquette placed in a position to deal with customers because it needs to be done & the position needs to be filled. is there still something called customer service training? cause I think this woman needs a few lessons... first to be taught manners & thereafter customer service. I shudder to think how long that will take!
