Do you know these women?

Okay.  There is a flower shop in my neighborhood, located just off a busy street, with a marquee sign next to it.  Instead of hot specials and rose deals, the sign always says "<first name>, PICK UP A FREE ROSE."  Obviously, it has become a life goal of mine to drive by and see "REBECCA, PICK UP A FREE ROSE."  In the years I've lived in this city, I have never seen Rebecca. I am coming to terms with the realization that it may never happen, especially since the names have trended toward the less common in recent years.

But yesterday's choice was a first.

To clarify: "IZZY KARLIE PICK SOPHIE UP A FREE ROSE."

What on earth is going on here?  Who is Sophie?  For that matter, who is Izzy Karlie?  Is adding a second name the next level of intricacy that ensures no free roses are ever doled out again--or is there a fantastic story here about Izzy Karlie and Sophie?  Are they two names drawn out of a hat?  Sisters?  Mom and daughter?  Is this Sophie's way of ordering Izzy Karlie to buy her flowers more often?

My imagination runs wild. 

Does anyone double-dog-dare me to go into the shop to get the scoop?
