But, I'm not really sure I understand the need for caffeine-testing strips. I mean, if you don't trust the people you're buying coffee from to give you what you've actually ordered, then I'm thinking you should buy coffee from someone you don't actually think will screw you over. And, really, let's say the strip detects something - what are you going to do, show the little strip to the business owner? What's that going to get you? They might just congratulate you. Or think you're hitting them up for a paternity suit - I like one of the comments on the article that the strip looks like a pregnancy test. And, it does have blue lines to show positive.
Well, you could always name the baby "Joe".
Here's the entire comment I mention above just because I think it's so funny. Yeah, so the person can't spell, doesn't do caps and is missing some punctuation, but funny trumps all that.
btw whos gonna sit around a cafe sticking home pregnancy tests into there coffee?
