Thanks Dr Singh -- all this streetcraft is performed as a racket -- not as a service -- the window cleaner washes your already clean window then expects to get paid -- the driver feels an obligation to pay -- the prostitute wants return clients [encores] -- but is not particularly interested in giving them anything in return for their money [all fours] -- and if they're drunk or stupid enough won't ! So yes there is ambiguity in my loyalties -- I am definately sympathetic, but I sure as hell wouldn't employ them -- LOL !
