Here is an interesting scene from the 2003 screenplay after Monroe employs Alma: (in 1974 or earlier)
Interior: grocery store: Wyoming: early evening:
Alma, a little older and a little less skinny, though still just as cute, is clerking at the grocery store. As she rings up groceries, we see Monroe, now a manager, wearing a cheap tie, flirting, smiling at her. Alma smiles back. The customer leaves. Alma and Monroe are alone. Monroe opens a box of Junior Mints and eats one.
Alma: "What are you smilin' 'bout?"
Monroe: (chewing, smiles even wider) "Nothin'."
Alma: "Gotta be somethin'."
Monroe: "Just happy, I guess."
Monroe throws a Junior Mint at Alma.
Alma: (laughing) "Stop that!"
Just then, Ennis walks into the store. Monroe and Alma immediately stop their flirting.
Ennis walks up to Alma's counter. Monroe hurries back to the office, afraid of Ennis.
Ennis: (pointing to the cigarettes behind the counter) "Two packs."
Alma: (not getting the cigarettes) "Who's watchin' the girls?"
Ennis" "They're outside in the truck."
Alma: (darkens) "I coulda brought home your smokes. 'Sides, it's way past their bedtime."
Ennis: (grim) "The quicker you give me the damn smokes, the quicker they'll be home in bed."
