I don't know about you guys, but for me:

it started with C girls using heavily filtered photos, eventually I stopped seeing C girls. I haven't seen any C girls (WLs). I wonder if C girls are still getting booked by any punters?

then J and K girls are getting price jacked up in all shops. Many K girls weren't worth the price anymore. and I've stopped seeing most K girls now. I wonder if K girls are getting booked by other punters too?

and now many J girls are not worth the money either, it's getting there
