It's like going to a restaurant for steak and chips and being told you have to pay for mushrooms and tomatoes even though you don't want them.
I think that's possibly only true of the cheapest restaurants -- that are offering cheap shit steaks in the first place; but it is exactly the situation with cinema now almost worldwide and they just charge the higher, 'all inclusive' price except for 'food' and drinks, which are added at an extortionate rate. (X-Men or Rise of the Machines or anything with Tom Cruise are expensive movies to make. I might go to see a stunt-filled 007 knock-off with Cruise but the movies completely reliant of multimillion dollar special effects don't interest me. Unfortunately they also help to pay for cinema seats. But if I want to see the latest Woody Allen or home-grown film, neither of which are expensive to make then I slightly resent paying Planet of Yet More Apes prices.)
With pro$titutes, there might be a small time element that justifies extra charges for watersports, hardsports or anal; or a fully fitted S&M dungeon.
But charging extras for what are largely personal preferences like CIM or DFK or RO is to my mind taking the piss. If someone has a good argument as to why those cost more I'd like to hear it.
There is a scam often used in Edinburgh lap dance venues: they will offer a 'special' service at twice the fucking price. Since they are too worried about getting nabbed, the 'special' service
is exactly the same as the regular service (which can itself be reasonably ok or shit). In practice, a lot of pro$$ies who charge extra for normal services because they don't like doing them will offer a mechanical service with it even if paid.
The only excuse, from a punter's point of view, for paying extra for such things is that there is a slightly better chance of actually getting them rather than finding out she lied on her profile.
In other words, being cowed by industry dishonesty.Sandy's of
Manchester used to have a long list of extras they were happy to throw in during the punt. It reminded me of a dentist that leans you back then uses your chest as a table for his clipboard and calculator (something sadly that is not completely unknown). Prossies generally are money-minded lying individuals with a mindset somewhere between a used car-saleswoman and the boss of Ryanair, with a fraction of the brains and often a fraction of the decency. Just as it is better to think 'Daily Mail' when reading the Guardian these days, it is better to think 'streetwalker' when dealing with a prostitute in a nice apartment. The mentality, mostly with less actual effort, is usually the same. With Sandy's, per-extra pricing, in my view spoilt what otherwise should have been a fairly decent brothel.
Never mind the over cooked tomatoes. Going back to the original comparison, it's a bit like the waiter asking if you'd fancy a proper plate for an extra tenner, or plastic cutlery to save a fiver.
