Would You Like Some Help Out?

Ever wonder what good this service actually does? I'm referring to when you're at checkout in the grocery store, and around the time that they're bagging up the last of the groceries, the bagger will ask you, "would you like some help out today?"
Who ever says yes? What are they actually "helping" you do? Let's take a moment to over analyze this shall we?

I always assumed that this is a service offered to the elderly, to whom the burden of lugging heavy groceries around can be too much, and the baggers are offering to help with the load, like a boy scout helping an old lady across the street. What I don't understand, or, what THEY don't seem to understand, is that this person is using a grocery cart, and that the process by which the groceries were delivered to the checkout counter wil be the exact same process by which the groceries will be transported from checkout to the car. In otherwords, "I was able to get them up here, I think I'll be fine to cross the parking lot." If the customer didn't need help pushing the cart around the store, its highly unlikely they will need help pushing it to their car. Perhaps they are accounting for the disparity of friction coefficients between the smooth linolium floors of the grocery store and the rougher asphalt of the parking lot. But only a very weak and very feeble person would notice the difference in terrain smoothness enough to actually require assistance. I also thought of the scenario in which perhaps moving around the store was manageable until that last item was placed in the cart, at which point it was all the strength the customer could muster to move the cart from the cotton balls isle to checkout, and going all the way to the parking lot with this final load would just be too much. A variant of this theory would be that the grocery weight WAS manageable, but the added weight of the grocery BAGS tipped the scales of impossiblity, therefore requiring outside assistance. I suppose these explanations are feasible, but they still seem unlikely. For a while I considered that maybe the lifting of individual grocery items from the shelf to the cart was viable, but the combined weight of several items in one bag was too much to lift, so that an employee would be required to actually lift the heavy bags from the cart to the trunk of the person's car. But then it hit me like a ton of groceries, how does the person get them from their car to their home!? This dilemma invalidates all the previous explanations. No matter what the reason, if a person needs assistance getting their groceries into their car, how do they get them out of the car?

I must conclude that the only reason this service is offered is as a form of lip service. We're going to make it look like we'll go the extra mile to lend a helping hand, but really, it doesn't help you do anything you couldn't already do.
