Bad customer service

I was in boulders last week, I went to the cooked food section to buy fresh buns. I reached the counter the was no one. The lady who was suppose to help me was busy packing food on the other side , I went to her and asked for her service with a bad attitude she came and helped me. Yesterday the 9th of January 18, I went to the same counter I found that lady with the other lady. I stood there waiting for assistance, the same lady by the name of Sylvia started talking with the other lady telling her how rude and nasty I was the other day, mind you I'm still waiting for anyone of them to help me.. I stood there till they done talking about me and that's when the other lady (not sylvia) came to help me. I confronted Sylvia if she's got a problem and told her what she did was truly disrespectful and so disgusting. Pls pick n pay management advice your stuff how to take care of clients. People like Sylvia deserves to be at the back as she truly lost her manners.
