Unhelpful Manager

Went into woolies, looking to tights, got told by a manager I was not allowed to try on tights, because the shape would change! I was not happy with that, she then called her manager, who was the manager of the ladies clothes section, explained my story to her, she then opened up the tights, told me she needed to check that they not broken or torn, as she would not want to be responsible for that. Proceeded to the fitying room with me, I needed to try on 2 pairs, as I was not sure of my size. She took one pair out, told me to fetch another colour so that they dont get mixed up. I told her im not going to mix them up, as I want to buy this tights, I just need my size. She clearly was not impressed with me for saying, as I could see it on her entire face. She then became very unhelpful, thinking that helping me was out of her way. Answering me in a snobbish manner, and then I told her she may keep her tights and her ****ty attitude.
