"""Downvote for what? Bad character?"""

No, I was referring to me being down-voted, for my snarky comment.

"""My point is merely that self-checkout is not only about speed, it's about personal comfort too."""

Sure, could be, but the particular "irritations" you mentioned I see as belonging to persons too self-absorbed, being the very definition of "first-world problems" for the Monk types among us.
