Pathetic Customer Service

Good day <br> <br> I am appalled at the pathetic customer service from the young white male (not meaning in a racial connotation, just for specification purpose), that serves the customers. I am not the only customer that complains about this boys terrible attitude. If he doesn't like what he does, as in his type of job, then I'm sorry don't take it out on your customers. I wanted to speak to manager and this young lady, was also quite defensively about the old products they had on shelf, just because the expiry date was in there opinion right. Even though, it was foaming at the top of the bottle. When juice starts foaming, it is not advisable for it to be sold as it would go sour immediately. i have purchased juice there before, and even though keeping it in fridge, it tasted like vinegar. I bought there quite regular, but sadly i stopped as the attitude of these people are shocking and quite unacceptable in my opinion, as I am in Customer Service myself.
