Here's a thought...

Go and see some gals that aren't advertising 15 and 30 minute rates.

And really give a gal who has a two hour minimum a shot.  I doubt you'll get many replies such as you're complaining about that way!

I have an auto response to take care of this, because if a guy sends me a one liner with no refs, I am not going to pull the screening info. out of him. My website is not exactly cryptic in what I require, and I still get dipshits asking "Are u available?" I will not even bother responding.

I hear what you are saying. All I didn't know was the exact time that I would be available.

I provided all screening information and wrote enough to show that I had read website/reviews.

One would expect a short reply (or even none) if the inquiry were cryptic, shall we say.

Happens on both sides of the coin..

I get these one liner emails "hey,are you available?" sometimes I get one word "Hello" emails.
These type of emails I delete I feel if a gent cannot provide a short introductory email about himself and add his references he is not serious.Even if he just wants to check on a certain day availability there is a way to word it so it is just not a lackluster request.Some are better on emails than others and I know at times people get busy but the short one sentence emails just lack warmth IMO.
You are doing fine

congeniality

congeniality and warmth are a must in any first time mails..she will feel comfortable..so will you..'i would love to see you' or 'i am excited to see you. always work..every provider has barriers you must cross..the 'first impression' barrier sometimes is the most difficult..
