I don't go to massage shops, but I'm also a bit fed up with this sort of arguments !

It doesn't matter if it's massage or FS, if you think a shop or agency is charging too high, just don't go there, stick with the one that you are comfortable with. We're talking about services here, not groceries, prices can not be compared this way ! Like a hairdresser, or a simple barber, you can pay from $10 to $100 in the same area, like the CBD ! Even groceries, you can find different prices for the same item from the same supermarket chain in different suburbs !
