So I was at Walmart today and I was walking through the main aisle with my cart, and I saw another cart coming out from one of the smaller aisles and so I stopped as to not bump into them. Anyways I was trying to be polite and so I walked forward so that I can see the lady (she was behind the shelves so I couldn't see her), and I smiled and told her to 'go ahead'. But as i said that she just gave me this rude/mean look and looked down and pulled her cart back. I was like WTH? I've never seen this woman before so I don't know what I did to upset her so much..
