Shoprite Checkers review: I am complaining about trolley porter

I have a complain about a trolley porter of morula complex I don't know his name but he is tall he has a little grey hair... It was at night maybe around 19:30 last week I was going to the taxi and he came to me shorting about the trolley like I am stealing and he was smelling alcohol I think he was drunk and I came back the next day I came and ask about him they told me he is a supervisor I didnt remember his name well but I think is thekiso how can shoprite give a person a this position while he is not responsible..
