Disgusting work attire

Saturday the 30th June at 08:10am I walked into Capitec bank to have some changes done to my account. It was fairly empty as it was still early before the crazy month end rush that all banks experience. I was number A10 as per my ticket number and while waiting to be assisted I noticed that a lady came from behind the desks wearing fully noticeable Capitec uniform and to my astonishment she had morning slippers on!!! I was disgusted. How does one who works in a bank which is a corporate institution wear morning slippers to work. When did this become acceptable? My number was called and guess who served me. Pinky the branch manager, the lady wearing the morning slippers. I asked her why she had slippers on and she said she only had heels and her feet were sore. What a pathetic excuse, my employer would not find that acceptable to come to work like that I would get a warning and be sent home. I request that this lady is taken to task because that is definitely unacceptable to be going to work like that and serving people. Standards of professionalism have to be maintained at all times.
