It will happen to you sooner or later. You arrive at the hotel room and find she is not the perfect beauty. She’s too fat, too old, too ugly or just someone you are not attracted to.
Sure, you can say “No thank you” and walk away (don’t worry, women can handle rejections better than men) but that can be awkward for both of you.
That’s why offering an indirect service makes it easy to decline her. After you have done massaging her, or shaving her pussy or showing her around the tourist spot, if you do NOT want to get intimate with her, simply accept payment for the indirect service, say “Thank you” and leave. If she asks you to stay back for a drink, or invites you to her room, politely say “I wish I could, but I have another appointment in 15 minutes”, and leave. No hard feelings. At least you got some practice with the indirect service and got paid for it. 😉
P.S. Btw, don’t be in a hurry to reject clients who look ordinary. Some of them have amazing figures, which you can’t see unless you both get nak*d. Also, in my experience, women who look ordinary tend to be more exciting in bed (they know they are not great in the looks department, and try to compensate by being more passionate in bed).
