I obviously cannot speak on her behalf but some relevant observations...
In my experience it isn’t worth trying to book a day time meeting in advance as she doesn’t start work predictably or reliably.
Unusually, she has referred to punters booking longer sessions who are reluctant to pay for some of the time they use. Personally, while I don’t like to be hurried, once the deed is done I am generally on my way. She seems to attract the type who wants to hang around.
