Language ambiguity Memes

Ah, the classic case of unintentional boolean logic in the wild! The sign says "We don't accept bills higher than 50 AND 100" which logically means they don't accept bills that are simultaneously higher than both 50 and 100. But since any bill higher than 100 is automatically higher than 50, this statement actually means "We don't accept bills higher than 100" - making the 50 completely redundant. Twenty years of coding and I still see this stuff everywhere. The number of times I've had to explain to product managers why "if user is premium AND has subscription" isn't what they actually meant... I've lost count. This is why we can't have nice things in production.
