I imagine it's a considered cost and risk actually, probably offset by the savings of having 1 cashier/6 tills or however they proportion them in morrisons.Stealing from self-service checkouts is another thing though!
I wonder how much shop lifting has gone up since shops introduced them.
My top theft 'but is it really?' tip: Krispy Kreme from tesco metro/express, they rarely have them on the self service tills so you're forced to put it through as a normal jam doughnut.
