Rude bahaviour from sakes lady

I visited the picadilly lenesia branch and was disgusted by the behaviour of the staff. I took 3 items and headed off to the fitting rooms. When i got there , there was this lady who has no s****s or any business ethics. She was literally screaming at the people in the line to use the fitting rooms signaling us with a hanger in her hand. I felt like an Exxon and she a prison warden. Firstly she was screaming at us we not standing correctly. correctly for her meaning in a tile and not an inch out. I tried to remain cool and collective. She was talking and treating people like she actually doing us a huge favour! It was my turn to use the fitting rooms. She refuse for my daughter to accompany me to the room to give me her opinion of the items i was about to fit. She told my daughter hey you don't u think of going in there, like my daughter is an Exxon. It took me time to calm down but i confronted her and gave her a piece of my mind. Screaming at customers and telling them not to move a inch from the line is just not on! I approach the manager but no apology on his side. Just that he did speak to her about her behavior.
