When sales ladies use sex, it is just eye candy. Maybe other people people have had real sex offered, but I have not seen this myself. I was at a car dealer and the sales lady was dressed like she was going to a wedding or a Christmas party. ( make-up, clothes, hair, nails ) The sexy lady thing does not work on me, as I have three lady friends with benefits that can offer me more than eye candy.
The same thing happened to me many years ago. it was another sexy sales lady situation. She gave me the full retail price on the car, I told her that I would check around and get back to her. She then said " Oh, is that how you think you will get out of here, are you expecting to get the car for free"? I said sarcastically. Free? Do you thing that would be possible? That would be nice. She knew she had went too far and tried to make a joke of the situation.
I went to a high end stereo shop back when stereo was big ( in the dark ages, before computers ) and the sales lady crouched down to show me the Altec Lansing speakers. as well as a upskirt view of her crotch.
I do not know if that was intentional. It was over a minute show.
