There is no doubt that screening and communication, especially for providers presenting themselves as GFEs who want to connect with clients, take lots of time.
Long ago I suggested to a regular friend, when she was raising her rate (not unreasonably) that she should give a discount for returners who didn't need screening, and a smaller one for those who made themselves easy to screen.
She did. And her number of regulars increased to the point that she didn't have to advertise for several months.

The above was a comment I made on another board, and Vorlon said that 1) short term gain is the name of the game 2) that discounts sometimes feel devaluing/disrespectful for the provider.
I understand both those observations, but remain convinced that locals need regulars, and vice versa.  
Here's a sort of illustration: I saw a friend last week who I have seen at least a dozen times usually for $7-800, 90 minute sessions. That's a good regular income isn't it? This time it was for a $2,000 session, she was wearing no makeup, reeked of weed and was out in an hour. I gave her what she asked for --  $1,000 "plus a $500 tip because we haven't seen each other for a while please."  
Of course in my mind the tip was for old times sake, because we will not see each other again. But I doubt she will understand the loss.
(And just to be clear, $4-$600 an hour is my ballpark, and the $600 has to be clearly very special.)

I'm not saying I think all providers think this way but some do.  And I agree with Lockstock in what he says.

And charged that much, I would definitely give that discount.  

The other thing I don't understand is providers not getting dressed up for regulars. I've heard that more than once and I don't get it. Regular or newby, I always look my best and have everything neat and tidy around me.  

It's a special experience each time, a not inexpensive experience and I always want to be at my best.

It's human nature to become relaxed with the familiar. Same with most relationships, including marriage etc.  Putting out the effort takes work. People naturally slip into the easier mode if they think they can.

I can understand cost of living increases, but exorbitant increases for a regular are a sign of contempt.

I second Anna here.  If anything,  I get more dressed up and fancy for my regular clients than new ones because they're coming around again and again which to me is very special.  I respect their hard earned money and the time they spend with me that they could be spending with their family or another provider.
