Is it a timewaster, or just nervousness? I asked him that
What it is, is a sure sign for you to end your communications with this guy with a very polite and smiley "Oh well! Another time hopefully!" in order to not end up sitting around in endless negotiations with someone who is probably not going to show up. There's nothing worse than spending an hour waiting around because that time's been taken from you by someone who's not going to pay you and that means you regret the whole experience and who wants to risk adding a(nother?) regrettable hour to their lives?!
On the other hand, I don't mind doing a bit of waiting around when I'm at home because I have so much else to get on with. I can get LOADS of cleaning done when I'm a bit worried that someone may turn up and see the state of my floors so that's a pretty good motivation, and then I'll probably risk sitting down and getting re-absorbed in whatever project I'm trying to make work that day, although that normally means two hours fly by and I don't even notice the no-show not-showing.
I know it sounds a bit cold to put it like this but if a client hasn't followed all my instructions, gotten to my flat and paid me, then I can't show him any more than polite but basic consideration. I sometimes apologise to real clients at the end of bookings that I tend to be a little brisk on the phone before I've met them only because for every great, real client there's half a dozen weirdos and morons so if I don't want to be on the phone, texting and emailing constantly, pandering to a bunch of guys who aren't even going to turn into paying clients, I have to keep things brief with them all. Real clients understand and I'm still getting my lovely weekly quota of them, all the more lovely for being understanding and perfectly capable of not having a big sulk just because they are politely informed that if they can't make a concrete appointment and stick to it, I can't spend the whole day responding to their vague (or worse, "flirty") texts.
Right, that was way too long a post just to say: Joey, if a potential client is making you spend this much time and effort thinking about him without even managing to fix up an appointment then he's not a very cost effective option, is he? It can be okay if you've got other non-escorty things going on at the same time but it's still not right for any non-client to be interrupting your day so significantly. I'm sure that if you explain politely and succinctly, he'll understand that you have real clients to be dealing with instead.
