Hi Joey, I would say it's up to you and your client to come to a mutually agreeable time, but you both need to agree on an exact time, unless you want to sit around waiting for clients to turn up that have no intention of doing so.
Clients will be clients. Let's try and put ourselves in their shoes for a moment. For some of them it has taken months to build up the courage of making that call, I think the thought of meeting an escort for the first time must be terrifying for them - if that's the case I would accept an apology email or phonecall to say that something came up and they couldn't make it but would really like to re-book.
For those that just don't turn up without giving the courtesy of an explanation I would tread carefully before accepting another booking from them again - this is the signature of a timewaster and in this line of work time is precious and time is money. I'd make it known to them that they let me down before and I did not appreciate it.
Some clients like to speak to escorts on the phone, it's an opportunity for them to voice the fantasies they want to live out to someone who will listen to them with an open mind. They probably don't know anyone in their personal life that they can talk like that to. But that's not our job. Avoid getting into long conversations about what the visit will involve, what you'll do to him, what he'll do to you etc. because this is sometimes all the client wants - a cheap way of getting their kicks without ever having to pay out more than the cost of a phonecall. That's not what we're there for and if the client doesn't make firm booking arrangements but lots of detailed phonecalls I'd point him in the direction of a good adult chatline as it's clear he has no intention of meeting.
It's the same with dating. If your date says to you on the phone "yeah sure we can go to the cinema SOMETIME", then that is the crucial sign that the intention is not there at all and you should continue looking for Mr Right. Intention is signalled by definite times and dates. If he says "yeah sure we can go the cinema, how about I pick you up at 8pm on Thursday?", how much more likely does that sound like it's going to happen?
I would say that during my time as an escort approx 80% enquiries did not follow through to an actual meet, and 20% did. Of course it's natural for clients to make enquiries without booking (how often do you shop around for the best bargain when making a purchase online or in town?), but you just have to weed out the timewasters. I think you develop a knack for it as time goes on. Learn to be firm and polite or people will just walk all over you and take you for a mug. If you are busy when a client wants to meet, tell them that time is not suitable for you instead of dropping everything to suit them, don't put them on a pedestal or feed into their ego. The world doesn't revolve around clients, there's plenty more where they came from and just remember that they probably need you more than you need them.
If you want to increase your likelihood of firm bookings, I think it all comes down to effective marketing. Think about who you're targeting... i.e. businessmen or students and what image of yourself you want to portray to potential clients i.e. rent boy (sorry to be crude and crass) or high class escort. Get yourself a good website. Think quality, not quantity.
Hope some of that helps, it's only stuff I've picked up from my experience as an escort. I happened to make every mistake in the book but I've always believed that every experience, whether good or bad, can be learned from, so here I am passing my lessons on to you!
Best of luck x
