Such and ******** shop assistant you have..

I came in at the branch in liberty midlands mall, the lady who I first spoke to was so kind, later on she spoke about opening an account for me, while I had sent someone to get my I. D. I told her she can assist the other customers who had come in after us. While we waited more customers came in and I was absolutely fine with waiting until a lady who wasn't even at the front of house came to me and told be to stand outside because we came last.. I asked her what she meant, she said because I came last I'm suppose to wait outside which doesn't make sense because when I came in she wasn't there.. I was at that shop like 15min and there was only 2 ladies at the front of the store and she wasn't there.. I'm so disgusted by the way she handled me. She didn't even ask the customers who came first.. Like we were basically the o ly customers in the shop before other people came in. She was rude.. Or maybe she was judging me by my dress code and thought she should just assist the 2 customers who were in formal wear.. I'm never setting foot at your store again.. Thank you for the horrible service.
