Sometimes the "too many questions/texts" is not always on the clients. I'll cheerfully acknowledge that there are those who "chat," and those who have several questions about services, limits, etc., but only ask them 1 at a time (that would apply more to testers than emailers, I imagine). And sometimes the answers you get back don't match the questions that are asked.
Once last year, for example, I was interested in hiring 2 escorts at the same time as a treat to myself. I contacted the first, and -- after making sure he was amenable to a 3-way since some are not -- I asked if rates would be different if there were a 2nd escort involved even if I was the only one being "serviced," as it were. His answer was that he didn't perform rim jobs. A total non-sequitur..
As a former escort, I get that "time is money" and that you can't spend all day talking to one person. As a client, though, I want to make sure I'm signing up for what I want, especially if I have something particular in mind. If someone says 3 texts is all they're doing (and I've seen that...on folks who don't list rates, so "how much" is one of the questions you have to ask), then I doubt I'll have enough information to feel comfortable hiring them.
(Just another drawback to trying to hire someone without ever having met or laid eyes on them first....back in the day, you could at least get a drink or something while talking/negotiating...*chuckle*)
