She refused to give me my 5 cent change

I went to buy 1 item at boxer noord street and i was servised by Nondlela Radebe, the item cost was 3.95 and i gave 20 rands so my change was suppose to be R16.05, she gave me R16.00 bck and i stood there n told her to please give me my 5cent change back , she gave this irritated look as if im annoying, and she said nothing and continued to help other customers standing in the que so i had to raise my voice again asking for my 5cent..and she threw me with a 10cent. i was ****ed n decided to live it there because she has disrespected me, imagine treating me as if im begging for me money and in the mean time is my change. Please sumone attend to this coz it aint the fist time its happenning, its common especially with The Boxer at Noord coz this was not my s
