Bad management

I visited MRP home on VA Waterfront Cape Town on 1 June 2025 before 11am. Firstly it took 5 min for a cashier to arrive at the empty tillpoint area although there were other staff in the area. Another customer was also waiting. Secondly I paid cash for my purchase and was due to receive about R44.30 change. She only had a R50 - finally after several minutes found notes to make up the R50 and asked me if I had coins. She called for the supervisor who told her to go to MRP sport store which is located next to the Home store. She returned, unsuccessful. She asked me again if I had coins so I asked her if she wanted to see my purse as I told her before I didn’t have coins in my purse. Finally after 5 minutes a staff member gave her a 30c and another staff member gave her a R4. I was told that the store only gets “change” on one day , which was Saturday so they will not get change for a 2nd day. The supervisor apologised for the situation which I found totally unacceptable. They were probably waiting for me to say that I don’t need the R4.30. Is this an acceptable situation and business practice.
