If your stride even hesitated, they were on you like vultures - and for good reason (from a sales POV). I had many 18-20 y/o acquaintances fall prey to the aggressive, attractive saleswoman.
Did they need to switch plans or carriers? Nope. She wasn't some scummy suit; she was a beautiful siren definitely attracted to him. It just so happened that she could give him the "best discount" on mobile plans and devices. It was coincidence that they never left with any of the girls' phone numbers.
Sex definitely sells.
Edit: To expand upon this a bit, I've noticed it with salesfolks that come to my office. It's always more "traditional" salesfolk that do it, say people trying to sell you a copier.
Though I'd say with regards to men selling things to women it is probably more common to have them 'talk down' to them. My mom was just complaining about how a car salesman wouldn't even talk to her about what she wanted and kept saying for her to bring my dad with her. I've had salesmen do it at the Apple store when I'm with someone who's buying a computer. They ask me what the woman should get.
