I wont allow anyone to hold my personal bank card

I was made to feel uncomfortable with what I believe in. I've been to rage store Evaton Mall when I tried paying the lady wanted to hold my card I kept quiet and let her do her thing. The 2nd time I went there again she did the same thing and I decided to voice up and tell her I'm not comfortable with her holding my personal card to swipe for me. I could see she didn't take it well. I went to the store again yesterday and there were other people in the store and she told them what I had said the other day,I explained to them that I'm not comfortable with what she did, they went on to tell me that's how things are done in that store. I told them it means I'm going to need to stop buying from them and left. I didn't like the treatment and them ganging up on me like that, didn't expect this treatment for a store I like
