ASDA KINGSWOOD HULL had no operator tills working 3 weeks ago at 08.30, was told they would not be working until 09.15. We had to use self- serve with a trolley full. We are both pensioners and my wife has severe arthritis of both knees and walks with sticks. Every 2nd. item the scanner stopped, the assistant ended up putting it all through (kept stopping for her), items were falling on the floor DISGUSTING! Complained with 2 e-mails and by letter, not response.
