Disgusted by the lack of service received from arrogance from Manager

i visited the Clicks store yesterday, for a small purchase, when it was my turn, i had to wait because the supervisor (Mandilakhe Bakhe) was busy processing a refund for a customer he was helping. The cashier stood helplessly for the manager to finish, with neither of them making any apology to me. I waited my turn and a merchandiser on the floor requested the supervisor to do a price, at this time i had already been waiting almost 10 minutes to be attended too. When i called the manager out and asked him why he couldn't apologies or see to me first, he completely ignored me and walked away. I was so disgusted because if this is the way that your managment deals with customers, then it's a bad example for your staff to follow, i was at the cashier for a while whilst he was attending to another cashier, so he had sufficient time to remedy the situation, but due to his arrogance, and lack of empathy for his customers he was not interested. If this is the way in which you want to service customers then i will change and inconvenience myself to go to Dischem instead, where things are completely different
