Rainbow Shops

I walked in the store to return a couple of items and as i waited for my turn in line a woman came up behind me and said
"Are you going to buy anything". I didn't understand why she kept asking me the same question. It was clearly known I was returning. When she asked me the same thing i just told her i don't know and that I was returning. I really had a problem with her coming at me from behind like that and she startled me at the same time asking me that question that didn't make sense when I was just returning. The lady clearly isn't trained properly when it comes to customer service.
