Steveo, I do understand where you are coming from when you say that so many of the posts on The Honest Escort are complaining. But, I think, what they are trying to show is examples of what NOT to do when contacting a provider.
And remember, it's not just the "complaints" of ONE escort that you see there. That handle posts for Sex Workers from all over the world.
Yes, this is a service industry. But anyone should know that one will get much better service if one is polite and respectful to the provider of that service.
If you are already doing things the right way and never turned down by the Lady you want to see, then you definitely do not need to change anything.
