A supermarket receives a claim for £50,000 from a customer in respect of injuries suffered when the shopping trolley dragged him down the travelator. The claim is contested at court. The brakes on the trolley were found to be defective. The supermarket’s defence is that there is a constantly repeated announcement to hold on to the hand-railings while using the travelator and, if it had been heeded, the customer’s injuries would have been minimal. The legal opinion is that damages awarded could vary between £500 and £4,000 depending on the court’s opinion on the extent of blame to be attached to the supermarket.
