Would most independent SPs get annoyed if you text or email them for a same day booking just hours in advance? I sometimes feel in the mood but then pause because I'm thinking what if they are busy or not in the state of mind to do this. I also don't want her to think I only do this last minute and disrespectful of her time. Like if I care about her, she would probably appreciate me booking days ahead of time
I have had many conversations about this very subject with quite a few SPs, and have come to the conclusion that it's as varied as the SP's personalities are. Here are two examples, close to either end of the spectrum.
One independent lady I met has extreme social anxiety and hates social chit chat. She loves Blow & Go appointments, because they usually minimize client-SP social interactions. Don't get me wrong, she truly enjoys her job and really gets turned on making men cum, but for her it is all sexual and no social. It is her preference. That said, it means that she is limiting herself to the less expensive end of the business, and has to be higher volume to make ends meet. She abhors pre-booked appointments and favours last-minute, same-day bookings. She doesn't mind the higher volume because she likes the physical interaction but not the social. Again, her choice, based on her preference.
Another lady I met had actually gone independent after a short time at an agency because she hated not knowing who she was meeting when the door opened. She is very low volume, and enjoys the build-up to the appointment as much as most clients do. She highly favours pre-bookings, sometimes months in advance, where she gets to know the person she will meet fairly well before they actually meet face to face. Upon meeting physically, she also likes to take time for a social chat before the events become more sexual in nature, meaning that she highly favours longer dates and those that start with a social engagement first. It's just her preference, and it's obvious to clients (well, at least it's obvious to me and to those writing her glowing reviews) that she's really into it because of the connection established during the lead-up to the appointment. That said, it means that she is limiting herself to the more expensive end of the business, but it allows her to be low volume and be more "fresh" for each appointment. Again, her choice, based on her preference.
There are no doubt many different preferences among SPs, falling somewhere within this spectrum - or outside of it. We are all different, which is what makes this activity so interesting.
So, my advice would be to always be polite (as has already been mentioned) and not to take it personally if her preferred approach doesn't fit with your current circumstances or with your preferred approach. You'll find someone that meshes with you.
