Re: 'Barter'
A friend used to be a taxi driver, pre Uber and pre-webcam days. Often teenage girls would try to avoid paying the fare by 'bartering' a flash of the boobs. One girl who tried this was rebuffed so then 'raised her offer', semi-literally, by proceeding to raise her skirt, revealing no knickers.
