Stumbled on this article recently and wondered - have any of the reputable Boston agencies considered accenting bitcoin for payment ? This would solve a major problem of girls (mis)handling cash.  I once heard from a fellow monger that a girl he saw claimed she was shortchanged and wanted him to pay extra when in reality he left her with a nice tip. Some girls choose to simply run away with cash in the end of the day never to be seen again giving this business bad reputation. Using Bitcoin does not require any bank account - simply use a phone app to send money like you would an e-mail. Also safe, because you don't have to carry large amounts of cash to the appointment.
