Rude manager Wanda wonker

So UNFORTUNATELY to my dismay i have no choice to shop at the shoprite store at delft mall. I went there today to purchase a cake for my son's birthday tomorrow he wanted a peppermint tart well low and behold they dont make it there i then noticed they were having a special with their brown bread selling at 2 for R20. The lines at the store was so ridiculously long even the express queues were making a turn at the back of the store. I went to the cigarette counter and asked the cashier if i can just purchase 2 loaves of bread at her counter because the queues are so long just for 2 breads, she politely shoock her head saying yes.. I then stood in the queue as my husband grabbed 2 loaves of brown bread. All of a sudden the supervisor by the name of Wanda upruptly and very rudely and unprofessionally all in our faces came saying HAAI HAAAI HAAAI HAAAI NO NO NO THIS QUEUE ISNT MEANT FOR CUSTOMERS HAAAI HAAAI HAAI to all of us in the queue as there was now people behind me. Now i have been in retail before for many years and there are alot more ways this incident could have been addressed. 2ndly do not shout at me and the other customers as if you are in a brothel.... The customers that come to this store does not need to be treated this way and all this because ur badge says supervisor..... All this because i chose to go close to home to a shoprite store.. Then she has a nerve to discipline the cashier infront of all the customers how unprofessional is that..... I was shocked i stormed out of the store but felt bad when i turned back to apologize to the cashier if i maybe got her into trouble... All she said was its fine ma'am... And this wanda woman was still going at this poor cashier infront of everyone when i asked her what's your name she stormed up to me flashing her badge telling me there you can take my ne its fine... Almost like she is invincible. Wanda my dear no one is irreplaceable you are also just a staff number on shoprite payroll just like that cashier who you embarrassed who was just trying to help the public. Think about that the next time you try to throw your weight around because your name tag says supervisor
