Tesco has introduced trolley locks (Image: NQ)But some shoppers have branded the change 'chaos'. A TikTok video watched more than 250,000 times shows shoppers without £1 coins queuing for trolleys outside the Basingstoke branch. Tesco said each store decides whether to use trolley locks with its management team. Some Tesco stores have used coin locks for years, while others do not. Tesco also urges shoppers to report abandoned trolleys to the store or Trolleywise so they can be collected.
