I have a similar one with my wife. We bought one of those thermomix machines and she was making some recipe - I think mulled wine or something because it required a 750ml of red wine. She pulled a random wine bottle out (we get all sorts of wine as gifts/bribes because she's a doctor), pours out the whole bottle and the thermomix only registered 690ml or something like that. She's all wtf and then reads the bottle and understands what's wrong. "Product of Israel".
