Self checkouts are usually quicker. So really there should be a premium for using them
They're not in my experience - they never work and you have to wait for the assistant with the key who's attempting to manage 6-8 tills at the same time, all having the same problem.
Bring back with the 10 items or less till.
I tried to use the fag kiosk at the local ASDA t pay for my butties, but even that have the self service till... with an assistant who's sole duty is to stand their and guide you in their usage. I don't know which is more pointless
a, a self-service till with staff supervision.
b, the member of staff that stands in the doorway handing out baskets and saying hello
c, the fool with the giant pointy hand on a stick that points out tills with little/no queue
