Put The Cashier Back In Her Place, While Making Her More Comfortable At The Same Time...

You decide to go femdom on this arrogant young woman and snuggle around Jane protectively. "Listen, darling, I'm sorry about the snarl, but you were flirting and we are exclusive. Still, if you want the name of our artist," you pull out your wallet and lay one of your business cards on the counter, "call me when you get off work and I can schedule you an appointment. Fair warning though, these aren't just gloves, they're high tech prosthetics that you can't take off voluntarily, they have to be shed like a snake's skin, and are not re-useable." You explain to the overly flirty counter girl.

"Oh, wow, I didn't know anyone around here was that committed to the lifestyle." She says, suitably rebuked and contrite. Then looks at Jean. "Sorry about flirting, I didn't know you two were together. I mean I knew you were shopping together but not like 'together-together'... Sorry." She finishes lamely.

Jean's much calmer now, and smiles at her, not wholly reassuringly. "Don't worry about it, just remember next time that if you see people in matching outfits including paired white and black furs, they're probably a couple, so don't try flirting unless they both initiate..." She says sweetly, and soon enough you are paid and getting out of there...
