Grocery stores could be a thread in themselves. I typically go at 7 am to avoid the moronic masses. I'm a very efficient self scanner. I know where all my bar codes are and what my products are called or their code #s. I bring my own bags and what is extremely annoying is the "remove unexpected item" (or whatever the stupid message is). I feel like screaming out, "I'M USING MY OWN F***ING BAG YOU DUMB S**T". That's Shop-Rite for ya. At least Acme asks the question, "Are you using your own bag?"
