Walmart Neighborhood Market

I always go to this walmart because its the right in front of my home. so i go today and as am cashing out i tell the lady good morning , and she just looks at me in a strange way, so i know she not upset because she was nice to the customer who had just left. so before she start swiping my items i ask her can you swip this item first because i want to open it and she does the face again . so as am getting ready to pay and she tells me dont use the ebt card yet and i tell her i dont own a ebt card then she rolls her eyes .. this lady was as rude as every i try to get her name but her tag was under she vest ... she was spanish with glasses little heavy set in registar 3 ......
