I am not sure if you can help here but would be glad if you could!
You may be aware that Tesco have stopped using both carrier bags and tray liners for home delivery. The customer is then expected to lift the goods out individually. This has already caused a significant impact for many disabled and elderly people (one only has to see the feedback on the Tesco Facebook pag, including mine). Requests to consider using bags for the disabled have been constantly refused and I am sure that this is discriminatory. Is there anything that can be done here? (I personally have to shop at Tesco as they sell the goods that I require for my special die, among other things, so not inclined, yet, to move elsewhere).
