I think a lot of WG's (not all) just take it as a 'personal affront' being requested a discounted rate, however politely or reasonably they are asked.
Example: I asked a girl currently very popular on here whether she'd consider coming out to see me. She's based in London for incalls and I live just outside London, no more than 45mins from her stated location. On her interview page she states clearly that she's willing to travel for up to 1hr for her outcall rate.
When I told her where I live she baulked at the booking because I live - quote -
'very, very close to her' (ie in the same small town, almost the same street). I managed to convince her that there would be no problem seeing me, and that in the very unlikely event that I'd ever see her around, I would merely feign ignorance. She was then fine with that. All good then!
Er,
no...seeing as she must pay rent for her incalls in London (I didn't pitch it this way), I asked her very politely if she might consider seeing me at my house for her incall rate because I was so close to her. No hassle for her, no rent to pay, little or no taxi fare even if she didn't have a car or didn't fancy Shanks' pony. Also, at her convenience, day and time-wise.
She went through the fucking roof that I might even consider asking her to reduce her rate for me, and 'did I think she was cheap?' WTF?! Stupid bint.
