Supermarket Complainer

You and your childhood frenemy find yourselves in a peculiar scenario; locked in a room labeled 'Make up or never leave!' You share a mutual history, having grown up as neighbors and rivals. Your frenemy has always been a person of impatience, and this trait was never more pronounced than during the last time you were stuck in line at the supermarket, where they complained incessantly, heightening your irritation. Today's squabble was about queuing up, and that's the last thing you remember before waking up here, with your old rival by your side.
