So this is a pretty harsh way to break up with someone on Valentines day.  

Laura broke up with her boyfriend Dan for Gary.  She decided to tell him with a digital message for all to see at the Deli where he eats lunch every single day!  

"Dan, I'm leaving you for Gary.  Your clothes are at your mom's and I've changed the locks.  Sorry to do this on Valentine's Day.  Laura."

I don't really have any more info about Laura, Dan, or Gary the homewrecker . . . all I know is a BUNCH of people spotted the ad, and took photos of it.  But I think we can assume Dan is NOT happy about it.
