I have tried the self scans but really struggle with them due to arthritis in my hands and knee joints resulting in me using a powered wheelchair. At least with the assisted tills l could place my few things on the belt and someone would pack them into my bag at the other end and even hang my bag on the special hooks on the rear of my chair if asked nicely. My other bugbear is the extra high shelves where it's almost impossible for a shorter person to reach anything down from. This has now resulted in my main food shop now being done on line and delivered to my door at a time to suit me, and no incliment weather to cope with on a bad day. There are still jobs being kept to do this, both in the picker who gathers the goods together, and the delivery drivers who are soo good at delivering it to my door. If l had one small gripe about this service though, l wish they would develop a reusable basket system to replace the plastic carriers they used to use, a large shop handed over the doorstep one item at a time, it's far more time consuming than the old system.
