Tesco boss warns of a potential spike in food bank usage amidst rising living costs. The supermarket giant urges Clubcard holders to utilize expiring vouchers before the May 31 deadline, offering various redemption options. The company name ‘Tesco’ originated in 1924 when founder Jack Cohen combined the initials of tea supplier Thomas Edward Stockwell with his own initials. Tesco has a long history, starting with a market stall in 1919 and evolving into a multinational supermarket chain with over 2,985 branches in the UK alone. The retail giant highlights the importance of using expiring Clubcard vouchers before they become invalid.
