Bad customer services from MABENA

I was at clicks soshanguve crossing till point time 17:37 name of cashier Isah Mahlangu. I had 5 rand coins to the amount of 300. A guy by the name or surname of MABENA came to the till, he said to me that in future I must not come en pay with coins in the after afternoon because they must cash up the cashiers that time. He did not even greet me. He just stood there en tell me that I must not come with coins in the afternoon, only during the day. His customer service is very bad, Clicks employees must take customer service very seriously especially the guy because the approach is bad. If there is any clause regarding coins can Clicks please verify that to me.
