Poor Management S****s

I visited Pick 'n Pay Liquor store in Eyethu Mall - Orange Farm on Saturday the 30th August 2019 around 10h40am. There was only 1 cashier at the tills with a very long quei. One of the customers whom happened to be in from of me was very upset on this, and he shouted to raise his concern and he asked for a manager. The security guys confirmed the store manager to be at the main shop while he was standing in front of us. As the customer continued to shout then he confirmed that he was a store manager. The customer confirmed that if he were to go to another branch (Sandton) at this time of the month you would not find a situation like this. This manager (in a short pants, a cap and a tshirt - with no form of identification what so ever) started to be emotional, telling the customer that he should then go to the Sandton branch and buy from there. I interfered with a lot of anger based on how he was responding to the customer. He told me that he is not talking to me but this other guy - I asked him to stop be emotional as a store manger and deal with the issue at hand; and confimed that I was going to report him. He then told me on my face in front other lot of customer that were in a quie that he doesn't care. I'm so ****ed off by this idiot because he will not be a manager without all those customers that were there - he could not even thinking about how this situation was affecting the poor cashier that was alone to serve so many customers. This idiot doesn't belong there, and I really need you guys to take action, otherwise you will continue to lose customers for Shoprite since a lot of people left the store to go and buy from Shoprite which is located on the other side of the mall. Can you please look into this and revert with remedial action.
