Sometimes I do, but reality is I can't always stay longer. Sometimes there's another person after me who's going to use my incall, I have frequent medical appointments, sometimes I have plans with friends, sometimes I'm tired.
I don't offer people presents with the intention of receiving something for free.. That's just me, tho. Yes, getting caught up in good conversations can lead to the appointment ending a little later. But if I have to leave, I have to leave. Reality is that if you paid for a certain amount of time, you shouldn't complain if the person is asking you to leave or is leaving when the time is up.
The message earlier wasn't that it's unreasonable to ask to go to the movies for free with a regular SP you're seeing for long bookings frequently, in my opinion it's okay to ask for that.. the message was that the person actually might refuse and it should not be expected.. if you want an arrangement with someone, you can also discuss it with her. Many SP will accept a reasonable arrangement. Some won't, not because they're cruel bitches who hate their clients, but because they don't have the time for it.
