My sister was at Walmart. She saw some lady with a cart full of tp, paper towels, wipes and cleaning stuff. The signs clearly say 2 per customer. So what did she do? Got a managers attention, brought her to the ladies cart and then my sister was given a 2 packs of toilet paper and a pack of wipes(cleaning wipes) and the rest was removed from the women's cart. All but 2 of each product. She didn't give the woman sas, or threaten her or anything like that. She got what she needed by acting like a grown adult
