I like self-checkout on balance. The stores have a lot more self-checkout stations than they had cashiers. Most of the time I'm buying less than a dozen or so items. The work of having to scan and bag them myself is hardly more than taking them out of the cart. It's way faster than waiting in a queue behind someone who's apparently buying groceries for two weeks for a family of 8 and then has several dozen coupons and finally is writing a check. Or waiting behind several such people.

I guess if I were buying two weeks of groceries for a family of 8 I might prefer the cashier to scan them and the bag boy to bag them for me.

Self checkout is just fine, except for UNEXPECTED ITEM IN THE BAGGING AREA.
