I've fvcked up a bit lately, because I accidentally bought decaf coffee beans, and the word 'decaf' was not in big/bold letters. Could I sue?

Not that I'm going to, even if assured that I could. The trouble isn't worth it to me one way or anything. I'm basically just curious.

A social mistake from me was made here and there, and I stubbed my toe which I'm known to almost never do. Spent a long time looking for house/car keys, found them in the fridge. That never happened before.
