Unfortunately waiting for the phone to ring is part of the business... I know guys who started in the early 90's (one of them still works in SF) he had to say in his place to pick up the phone because cellphones were very expensive and costly to maintain... at least escorts now can go to they gym, take a walk, etc. while carrying their iPhone waiting for a client to contact them and make in one hour what it would take others several days of minimum wage hard labor to make. Enjoy!
you're not alone... plenty of folks out there in similar situation.
Exactly folks go out for a reason. Unfortunately now a days you'll see them checking their phones in a bar too.
