Review Appalling service at Raslouw Postnet (Centurion)

I went to Raslouw Postnet this morning (23 July 2020) to print a PDF from a removal. I had to wait for the 2 assistants to finish their discussion before being allocated a pc to print. After printing, the pc persisted in informing me that the removable stick cannot be removed as it is being used. I closed every document or file that was using it to no avail. I then asked one of the assistants for help, who just told me to remove it without using the safe remove button, to which I objected that sometimes doing that is the cause of many corruptions of disks.
She was very rude and just ordered me to do as she says. Even when asked for her name, she told me that she won't give it to me as she has rights too. Why are they not wearing name tags? Long story short: the manager at the time (Unita?) just reiterated that although there is a chance (high) of disk corruption, I should just remove it without using the safety process. What about POPI Act? Typically, when a disk cannot be ejected safely, somewhere in the LAN someone by be (1) having it open, or (2) copied it, etc. Disgusting!!!!
