I was in ASDA this morning buying a newspaper. Clear signs saying max of 3 of any one item. A women puts 12 cans of potatoes in her trolley, I told her limit was 3 of any item but she just ignored me and carried on adding another 4 cans. Everyone was looking at her and her partner/husband was looking slightly embarrassed. Great when she got to the till and they would only sell her the 3 tins.
