Shocking attitude and service

I recently stopped at a Caltex Garage in Pinelands ,on Caversham Rd in Pinetown ,KZN. I have used this garage many times as i live in the community there ,but the service has never been good .On the 11\04\2021 i had stopped for fuel and to buy something to drink in the fresh stop store and i asked the teller to please allow me to use the toilet ,and she said no. I asked why and she continued to say they don't have any .I find this absolutely poor service .I told her I needed to go and they continued to refuse ,so I was forced to go around the side of the garage to urinate ,which at my age of 52years was very undignified .Some of the attendants watched and laughed . I am a regional manager for a large national clothing company ,so I am very aware of what service is about .The service I was shown was absolutely unacceptable and degrading ,thanks to Caltex Staff .Not only will this go to the normal social media platforms ,but I will be taking this up with Caltex National Senior Management .If this is the type of service you allow into your fold ,then I am afraid you will never see my money and the money of all the customers I will be sharing this with .Thank you .
