The crumb leavers. You open up the pot of 'Fuck Me If It's Not Butter!!!!' and find it covered in crumbs. "They're only breadcrumbs" they say, but how old? And are they bread? Can you guarantee they're bread? I'm not eating 3 week old mystery lumps. Stop being disgusting and get some basic spread sharing etiquette. [also see jam butterers]
The upside down bottle right-way-uppers. The scientists at Heinz spend years of their life designing bottles of ketchup that stand on their lids to help you extract every last dollop. Society moves on. Some lids go on the bottom. Get over it.
Champagne spooners. You really think that champagne keeps it fizz if you put a spoon in the neck of the open bottle? A spoon blocks gas? That famously chunky state of matter? Sure, because I'm constantly having to mash air with a fork to get it into small enough pieces to breathe. [eyeroll emoji]
