Engine N3 truck stop Petrol attendants really hate their jobs. They absolutely don't want to work there and it shows to us the customers

On Saturday the 8th of January, at about 18:00 I stopped by to get petrol at the N3 truck stop Engine garage just off Leondale and Katlehong. I asked the lady to pour petrol and the amount. While pouring she was distracted by having a fat chat with her colleague which lead to her pouring more than I had requested. I unfortunately only had the exact amount of money for the Petrol I had requested and thats when she lashed out demanding that I have to come back and pay (for her mistake). I was initially willing because of Ubuntu but the way she went on, it was as if she was entitled and didn't even want to hear anything I had to say. Calling her rude would be an understatement, I have never in my life, been made to feel like such a ********. I felt maliciously attacked. What makes this worse is that I actually don't have the money that she was forcing me to pay as I am unemployed and with the unemployment rate at its highest. I was shocked at how much that lady doesn't appreciate her job. Please engine, I would rather have a system where I pour the Petrol myself (I honestly don't mind) because I can't be treated like dirt for a service that I am paying for. I have never in my entire life, met anyone so obnoxious. When she was done treating me like feces she walked away and I just drove off having made to feel like less than nothing. I didn't even take a look at her name tag,but I pour Petrol there all the time and I could easily identify her. Please train your employees to be a little bit more professional because the immaturity shown by that lady, just shows the level of respect she has for the firm and that is none whatsoever.
