JUWS

What is happening to G Man? Roy, Joe, Jerry and I had the same bad experience with Jon a couple of weeks back. On top of that Romeo (the manager) has messed up my first two appointments.

SA, I know you mean well, but you are making assumptions that probably don't hold up for many of the guys who work in "spas."  First, that they have a space to host clients in NYC, much less in Manhattan.  Second, running an online ad requires a credit card or bank account to pay the fee.  It's not likely that many of these guys have such a thing.  Finally, as has been discussed here many times, some guys may need to stay "under the radar" for immigration reasons, or worse, are beholden to a "handler" of some kind who holds their passport and calls the shots.
Going freelance would be a big step for someone who perhaps is not fluent in English, or confident in being able to negotiate terms with a client.  The spas have the space and a more-or-less reliable flow of customers.  Yes, the money sucks for them, but it realistically may be the only viable option for many who work in them.
