Ahhh, yes, those tossers!
It didn't take me long to learn about TWs and to set up some ground rules to avoid them.
Everyone is different and has an individual way to run their own business, but I have chosen not to display a contact number. I don't offer text or phone call services, so this isn't a problem.
But my ground rules are, once a booking has been agreed, then it needs to be made on the online system before any of my details are given out. This weeds out 95% of TWs as they want to avoid the negative feedback. I also find this helps weed out any potential dangerous clients, as making a booking on the online system leaves an internet paper trail, so helps keep me safe.
With emails, I religiously check for any previous messages and also the private notes section, real handy!
There's only been one time I was caught out, and that was last week. He had booked before, so had my number, but the booking never happened, can't remember why, it could of been me who cancelled. But he texted me for a booking request last week, and once things had been discussed and agreed, I asked him to book online, he said he couldn't get online, but I stood my ground, because I hadn't actually met him before, I wasn't going to put myself at risk and bend the rules for him. And good job I didn't! He very quickly became nasty, verbally abusive and started threatening to expose me!
He then claimed he had spoken to a shop assistant near me and claimed the police new about me and I'd get a visit. I laughed. I havnt broken the law in any way, and throughout all the abuse, I stayed calm, polite and professional in my replies. And as soon as I said, "if that's the case you will then get done for harassment" I didn't hear a single wink from him, surprise surprise!!!!

and he had been calling ME a time waster! Paaahahahaaaa, don't make me laugh! My profile is very clear about my terms on bookings!
