Disgusting Service

I went to put in petrol tonight at the Caltex in Kuilsriver, filled up and swiped my card. The transaction went through according to my account and sms that I received. I was then asked to swipe again due to network errors. I refused, as I have heard of numerous ****s regarding this. The petrol attendant then called the Supervisor how asked me to do the same thing. I asked to speak to a Manager, as I was not going to swipe again. The Manager came over all casually dressed, not in branding clothing, with a nonchalant attitude. Didn't really greet or ask what the situation. I then just jumped straight into the situation and that I was not going to swipe again. He the proceeded to explain to the Supervisor what to do while I was talking to him. I told him that he was extremely rude by doing that and not allowing the customer to explain. His response was thank you and I have heard this from previous customers. He then walked away! This is NOT how you treat your customers!!!! I think that it is extremely disgusting that someone like that is running a very busy garage. The supervisor then explained that they have a standard form for this situation. I am extremely ANGRY & DISGUSTED!!!!!!
