4) The "odd change" is often very useful, especially on a busy nigth when you're running out of change. I know this because I've worked retail plenty of times myself. Besides which, when I offer it, the tilljockey usually says "yes, thanks", even pausing to wait for it. Hate people for being stupid and inconsiderate, not the opposite.

5) Those things can be confusing, especially as a (a) they're often cunningly concealed behind the bloody lotto cards, (b) they're not remotely standardised, so it's a different arrangement in most shops, and (c) my debit cards are nearly symmetrical, what with the hologram and chip being placed exactly opposite each other, and my being colourblind.

All other points are pretty valid though. Especially the one about putting things back on the wrong shelf - the bigger the shop, the more people think they can do what they like.
