I am using Asda every week. I do like idea of scan&go, I can pack product my way wthout till rush. Yesterday when I did my weekly shopping, I had to join queue with customers self scan products at till. I was not allowed to use bascet one because I used trolley which was a bit strange. I dont have to scan products at till so I would be quick. What point use own phone to scann products,when at the end still have to join queue with everyone. Don't get any quicker.
