Juliette, I assume this man has done this more than once? Otherwise, it's just a one off no show which could have easily been predicted by his bombarding with texts/questions and irritating though it is, as has been explained before ad nauseaum it is part and parcel of our job. If this man makes a habit of pestering sex workers, please do amend your post to make this clearer.
Once again, this sort of thing does not belong in the warnings section where it could detract attention from people who pose a serious threat or cause continued or extreme fear and/or distress with their actions. The purpose of this section, whilst it is intended for persistent timewasters and pests who are never likely to actually meet any of us in person, is no less serious than the main Warnings board and it is not a place to rant about somebody who just asked a lot of silly questions on the phone, or booked and didn't turn up once. Please try to keep the Warnings posts for those who deserve them.
