Disgusting sad service.

I work across from The Pantry and purchase a Capuchino daily from them. Today I was horrified at the till operator that assisted me. I gave her a R100 note, and her reaction was very disgusting, she asked me if I don't 'have a bank card as she doesn't have change, but then she opened her till. I said I don't have cash on my card but cash on me, her reaction was OH my God. I said why are you saying oh my God when you have change in your till then she said how do I know that she has change, so I said your till open I can see, her reaction was awful, she made funny sounds and disgust on her face, I told her you don't treat a customer like this, there was no apology but just disgust on her face. It is so sad to see this. The Pantry is a very upmarket reputable place where my colleagues and I always go grab coffee lunch or snacks and to receive this type of service so early in the morning was so SAD to see. What happened to good old customer service and friendliness... The Pantry please train your stuff courtesy respect and client centricity.
