Just a quick reply, I havent read all the posts yet. But wanted to say the IGA Foodliner we go to has the same policy. They insist on taking things to the car no matter how little. That store is in Boyd, Texas, very small town. My town is even smaller, Rhome. We dont have a store, or even a traffic light :)
DH and I moved out here to get away from Dallas in 2007 and love it. However, there is one fellow who tends to toss the bags in the trunk a bit roughly. After a couple times of him doing that I let him bring the items to the car.. if we try to refuse he says "store policy", and when we got to the trunk I told him to place the items in there gently, that was my policy :)

I've had a chance to read all the posts now. Personally I hate using the self-check because of the hassle. Continued beeps and waiting for someone to appear to correct and get things going again. Seems as soon as I start to build up a little speed, wham, another beep. This is VERY annoying to me if I have frozen food items sitting there thawing while I wait on one person who is usually manning all the lines at once. I will only go that route if the other lines are very long.
Still, in spite of this I couldnt help but wonder if this is how people felt when the first self-serve gas station pumps came along.. and then later the first entire stations that were self-serve. My mother has told me there used to be a man or a couple of men check the oil etc when he pumped the gas. Self-serve stations cost him his job.. but then, eventually enough time passed and the next generation saw that as the norm. Time marches on, I just wish the automation would slow down.
