Shell - Dlamini Service Station Unclaimed

So I went to shell filling station in Dhlamini, Soweto, where I waited in the line outside to use atm. It's extremely cold today and because I could the patron in front of me, I decided to go inside the convenience store. This did not sit well with employee Martin McKay who started hurling insults at me, even after I asked him what if it was raining would I be expected to wait in the rain. I literally stood in the store for 5 secs before I was up next. His fellow employees watched on as I had a screaming match with this individual who also threw in a F bomb. Even after I threatened to report to him, he dared me to.
