****** My change R50 bucks

Good day

I went to Engen one stop express in Alberton next to police I l always pass there most of the time when I went to visit my daughter is one of my favourite I like their ****in especially the blue berry one but to cut the story short I went there today to get some cash at their atm store then I bought some ****in and sparkling water so when I was paying I gave the R100.00 and when I was paying for my taxi fare I realised that he gave me a change for R50.00 because I still remember I wanted to pay with R50.00 then I told myself that I need a change let me pay with R100.00 my charge was R12.00 I don't remember the guy name but he is short and dark my surprise its he did not give me a receipt so I don't know what happened I regret paying using cash because usually I prefer using my card instead of cash lesson learnt.
