I usually go to Cascade and I've never had that problem with the girls I've taken, and I go for the really feminine ones. Some have nearly invisible come, but that's just to be expected. When in doubt I just ask and I've never had one lie to me.
There was one girl who had trouble coming, and it took her nearly an hour to manage it, but she got there in the end.
Another option is to tell the Papasan/Mamasan what you want.
