Went to Walmart on Mutual Way in Appleton, WI on Thursday Feb 16, 2023 in mid-morning. I paid at the self checkout. There was one female clerk there watching people checking out. She was an older lady with a walker. There were only a couple of people checking out. She hovered over me so closely to see that I was not stealing, I asked her if she needed something. She did not respond. I was so fricking uncomfortable I almost asked her if she wanted to do the checking out herself. Geez, Louise, give the customer some space and DO NOT ASSUME THEY ARE STEALING. I have had clerks at this checkout tell me that I did not pay for something in front of a lot of people even after I pointed the item out on the checkout tape. After I proved I paid, they just walked away,,,no apology. I almost came to the point today, where I was just going to leave all my food there and just walk out. Do somethng about these employees who are nothing but a bunch of asses with no people or customer skills whatsoever. And one more thing. half the time the prices posted in aisles do not match the checkout....Many times I have been overcharged at the register according to the price posted in the aisle. Today, while I was there, a woman had taken a picture of the price of an item and pointed it out to this lady with the walker.
