I was at a party with a mid tier VC partner as he described a hotel off sandhill where there was a set night of the week where the women at the bar were all prostitutes. You'd buy one a necklace at the jewelry shop around the corner, give her the jewelry and receipt, and take her up to your room. Afterwards she'd return it for cash (minus a small "restocking" fee).

He seemed bewildered by the whole scene, but was very matter of fact about it/I don't think he was bullshitting. This stuff is definitely happening in a regular and organized way, albeit well above my pay grade.
