Gillian's Found Photo #25

I love this picture, this couple looks like they know how to have a good time. The drink on the table looks like a margarita which would put the location in California (you kind of expect to see a bottle of Crown Royal, with the blue and gold felt bag), but that's just a guess. The clothing says 70's.

What is the gesture he's making with his right hand? And what's she got in her right hand?
