Poor customer service

I went in to pg glass newton park for a vehicle inspection. After being asked by Louise for my drivers licence and reference number I said I need to fetch it in the car. I went out and returned and sat in front of her. She was busy on her tablet. I did not know what she was doing as she said nothing while I waited and I therefore didn't know if I am supposed to wait or what was happening. After +-2 minutes of waiting, I said to my daughter we should come back another time. It was only then that she said she is logging onto the system to do the inspection online. I said to her that she could just have acknowledged that we were there and said she's logging on. She said she was just doing her job, I them said that that is poor customer service to not acknowledge someone. She again said she is doing her job and haven't I had an inspection before, to which I rep****, I have had inspections, but not with such bad service. She then said she can't look at me and type at the same time because there are a lot of buttons to press. My problem is not with waiting. Her bad attitude and poor service was a problem.
