I love seeing "no texting" in ads. I only text because I can't make phone calls to setup appointments. I work, and I have people around me that I don't want to hear me ask "do you do babeback blowjobs?" out loud. I usually text, figure it all out and I'm happy to call when I leave to get into my car or when I'm outside the hotel. But honestly, I think a lot of providers are missing out when they put that in their ads. I know they get a lot of texts that lead to nowhere, but the phone calls must too. Also, you are likely to get less people contacting you (like me).
Also, when they say "call/text me from your real number" is just another way to say, good-bye. Why would I use my real number? Do any hobbyists (or providers for that matter) use their real numbers? And if you do, what the fuck is wrong with you?
