People use them because they put less staff on the tills.
So if you don't use self-scan it takes longer. In my (no ex-)local Tesco the staff were told to encourage the use of the self-scan also.
Which is my point -- they are replacing people with self-scan and trying to force customers to do the work of a checkout assistant. So they're both contributing to unemployment and having customers do unpaid work.
I'm not exactly Mr Sociable myself, but I'd much rather the men and women in the local Tesco store kept their jobs and be served by a person who can do things like serve alcohol and pick things up from behind the counter.
