A terminally-ill grandma claims a Lidl security guard banned her from shopping at her local store because he "mistook her for a druggie".
Sick Karen Sahiti, 55, says she was left "devastated" when a male security guard told her she would not be allowed to return to the store.
She says she was confronted by the guard when she popped in to buy beer for her son and use the toilet earlier this month.
