I am envisioning some hang up at the checkout point where, at Walmart, the clerk pulls open a new bag that is on the rack. For reuseable bags, does the clerk hang them on the rack to fill them? Is there a problem with the larger totes? I used to bring my own totes when we had a grocery that was "bag your own", but since it is gone, I haven't tried it at the only grocery store left in town. (Walmart) Perhaps I should make it as inconvenient as possible for them, just as a matter of principle? (lol)
