to answer your question K, and I deal with this all the time in my biz too, you only get what you pay for.
For eg: If I had an average looking, average service SP, for $140.00, I'd say: ok, well, I didn't pay a whole lot so I can't expect much. But if I pay the going rate of $220 - $240, then I expect to receive pretty good service from a pretty good looking sp. Same as if I pay $260 - $300, which is a better than average price, then I expect better than average service. Same as if I were to pay $350 and up, she better be god's gift to my libido and leave me brusied broken and drained when she leaves.
I hate doing this but it is a method that everyone can understand: Compare any product or service to the auto industry. One can't expect the same quality in a car selling for $15K as one selling for $100K and to count on or demand that quality in the cheaper version, is ludicrous in my books.
Or a comparison that might be more palatable to the ladies: compare diamonds. One can't expect a $1000.00 1 carat diamond to be of the same quality as a similar weight diamond costing $15 or $20,000.00. Now if one pays $15K for a 1 carat diamond, it better be flawless or I'd feel ripped off.
I guess another thing that gets us guys (me) is when the lady in the photograph isn't even close to the lady that shows up. There is a lot one can do in photographs to hide flaws with lighting, poses, placement of a sheet etc. I guess this is also why I have a beef with the stats posted. Now I know many agency owners say "what do you want us to do, measure and weigh them"? I say "yes, of course. If they're advertising themselves at 32 24 32 then as a responsible business owner, you should confirm that. To me, that is like me advertising a bird'seye maple armoire for $12K and then building it out of B grade maple veneer.
I guess it boils down to if one pays a less than average rate, then they can expect a less than average service. If one pays an average rate, and receives less than average service, one feels ripped off. (and for the record, the average service in Toronto these days is way above average IMO)
