Here's what I would do... ALL FOUR.
SFMF: SFMF is here in the natural habitat of our subject, the retail establishment. Some of SFMF's viewers may know this as "a store".
Co-worker: What the hell are you talking about?
SFMF: Our subject appears agitated, not approving of SFMF's unwelcomed entrance onto her territory.
Co-worker: I don't get it.
SFMF: Our subject is growing hungry, waiting to stalk her prey, commonly referred to as "customers".
Co-worker: I'm gonna go in the back for awhile...
SFMF: Subject invited SFMF to the mating grounds, otherwise known as the fitting room. *winkwink*
Co-worker: What are you doing?
SFMF: Subject acknowledges the initiations of courtship.
*SFMF does Riverdance*
Co-worker: Gee, I didn't know you were into that...
SFMF: "Oh no...you're not fooling me THIS time!"
