About this scene
Big-box store cosmetics section, mid-afternoon. She's a curvy Latina redhead, in jeans and a tank top, browsing the lipstick rack. The flash is across the aisle at the perfume display. She walks past the rack once. Twenty seconds later she crosses the aisle and stands two feet from the rack he's near. Her shoulder is almost touching the rack itself. She picks up a perfume tester, sprays it once on her wrist, and stays in that exact spot for almost a minute.
What to watch for
The proximity is the entire video. Most browsers maintain three feet of personal space from strangers. She closes that to one foot and holds it. The wrist sniff is the cover. She does not actually smell the perfume. Watch her right shoulder. It stays oriented toward him for the duration. Her face is angled at the rack but her shoulders are not. After the minute she puts the tester back, walks away, and circles back to the same rack three minutes later.
