Measurement Miscommunication ^^;

So, I'm out with my husband and his aunt at a seaside restaurant. We're about to have dinner and we initially ordered waters but he decided he wanted a little beer with his dinner (he was driving so he only wanted a glass).

He turns to me and says, "May I have a small beer? Just 30 ounces." Without thinking I said, "Yes." Then I said, "Wait a minute, did you just say THIRTY OUNCES?!"

He meant .30 litres of course XD

I pretty much gave my husband license to drink 3/4 of a 40 without even thinking XD
