Customer service non existent

I have been a regular rondebosch pick n pay customer but due to work i have started shopping at pick n pay st Peter's square in observatory. Today I had the most terrible experience and will definitely not be visiting that store ever again. Reggie, the deli manager, has anger issues and does not know how to communicate with customers, as I did not appreciate him shouting at me and telling me if I could not make up my mind I must go stand at the back of the queue. This man was shouting at me in front of a line of customers, Embarrassing and belittling me, I asked why if you know its busy why do you only have 1 person serving customers. Can you please explain how this person gets to manage a department and people when he does not know how to communicate to a customer, I can but imagine how he speaks to the staff in his department. Furthermore a manager has a certain standard to uphold, not to mention the pick n pay brand. When I frequent a store the service I receive, the products in the store and the cleanliness of the store/staff is taken into account, pick n pay st Peter's square has alot to improve on. I will not be visiting this store even though it was convenient being close to work. The st Peter's square store can learn alot from pick n pay rondebosch, from the security to the till packer, they know of client services.
