At all of Sainsburys, Asda and Morrisons I've regularly placed my own
backpack in the bagging area. Once the supervisor flicks a switch it's
perfectly okay to load up the bag directly without having to verify every
single item. Maybe some other supermarkets use less flexible equipment?

The first question Tesco ask you is "Have you brought your own bag", at
which point you can put it on the bagging area and it re-calibrates the
weighing scales.

The machines at my local Sainsbury's don't seem to get on with rucksacks
whenever I've tried that. They can cope with normal cloth shopping bags
of the sort I seem to acquire at conferences.
