Nando’s this weekend - as long as they bring and elderly friend or relative with them. The restaurant chain will slash 50% off the total bill (up to the value of £20) when they dine in their local branch with someone over the age of 65 from June 7 to 9.Bosses say that the ‘NanGo’s free’ promotion is to celebrate our much-missed grandparents or elderly friends, who have spent the best part of a year in isolation.
