Arrogent rude manager. POOR consideration

We were enroute from Marloth Park to Durban yesterday when we stopped at TotalEnergies N17 (Fourie Street) to get some stuff from the shop and top up the water in our car, which was over heating. We did not want to clog up the forecourt and went down the side to get a 2 litre water and go through the fairly tedious process of opening the header bottle S L O W L Y. letting water come out. Fillng slowly with the car running etc. The woman manager came around and INSISTED we leave. She was unreasonably RUDE and OBNOXIOUS. We never left we filled the header bottle and made our way. I am extreemly surprised and dissapointed in this experience.
