Terrible service at Postnet Glenwood

I was charged a R5 'usb fee' which I thought was exorbitant and something I have never encountered before. How can it cost R5 to print something off a usb? Additionally, the assistant did not have change, so she simply did not give me change - told me I could get my change when I next came in! The sheer utter cheek of it. Imagine if I asked for a service, then announced I couldn't pay, and told them I would settle up when I next came in..... Thing is, I won't be going back. There are other cheaper, more pleasant places to print documents or send parcels.
