There's perhaps too little of these objects in the picture to be called a still life. Also, the lighting isn't very interesting (flat). And since we don't know anything about the call, I have trouble relating. (Though I am a big fan of starbucks!)
I think a closeup of the contents of the cup might have been an interesting still life. Or at least maybe a top down arrangement of cakes with the startbucks cup as the "non-cake" element, taken from the top, with good light. Maybe next time.
Beaut..i hate product placement, but this seeks obviously to go beyond that and illustrate corporate america, or maybe its lesser cousin, impatience of youth.
Your title tells me you're waiting for the call but I had to go looking for the phone, it's almost lost down on the bottom. I would have liked to seen just a bit more of it. The focus is on the table which, while it has a nice pattern is really rather boring. If the focus had been on the coffee, phone and snack with the table in the background this would have score much higher. A 4
