Disgraceful and unprofessional behavior from manager

On Wenesday morning between the 07:00 and 07:10 I stopped at Total fuel station Kenilworth. When your petrol jokey approached I never noticed that he was the manager.

Upon the request for the amount of fuel I asked him to take 200 cash and 250 on my card but he seemed to be very confused as to what I wanted and so I had to explain it to him again and he seems very agitated with me at that time already. Whatever happened before me arriving at your fuel station is not my problem but anyway, I let it slide until he finished dispensing my fuel and finishing his coffee at the same time, how unprofessional to begin with.

When he was done he came to the window to collect payment with me and my passenger as witness as I held 2x R100 notes out my window. Again he asks me so how much cash and how much on the card and at that point I told him and I quote, ( bro it's not rocket science man, here I'm giving you R200 now you do the math.) Please go to your cameras and check the footage cause upon my saying that he started pointing at me and telling me about who must pay what if mistakes are made. I can't believe that guy is the manager, dirty and rugged, unshaved and drinking coffee whilst serving customers. Is this the kind of service levels Total Energies can afford?
