Do you organize the order of your groceries in the checkout line?

I'm just wondering what the title asks: do you organize your groceries in the order you will check them out, if doing self-checkout, or arrange them on the belt/counter in a standard checkout line, in the hope that they'll be bagged in a specific way?

I didn't know there was any other way people do it, but just learned some people prefer to checkout/bag without pre-arranging things. I'm kind of curious to see what's more common, or if there's some other options I haven't considered?
