Chad Johnson Shades Evelyn Lozada?

Back in 2011 Evelyn Lozada famously slept with Chad 'Ocho Cinco' Johnson on their first date after he flew her out to Cincinnati [click here if you missed that]. 

Now Chad is warning others NOT to do the same thing...

Over the weekend Chad shared a picture of a generous tip to his server along with a message to 'never have sex on the first date.'
