I can definitely dig the organized bagging thing. One bad bag of lunchmeat found in the back of your car with the can goods "I`ll take in tomorrow" will put you in that mode.
I too put everything on the conveyor in a specific order and make sure the checker understands when I ask, "can you bag these the way I have them organized?" I`ve had pretty good luck so far!
And Eric, NO, I don`t have a super strong swiper arm. I think someone cast a self scanner hex on me as I`ve never broken the swiper in the regular checkout.
