cat 80/100 cat 150 ?

[84lukechan]

first of all , sorry for noob question . I am a newbie :) . I know WL in geyland are classified as cat80 or cat150. Is this classification depend on how much time they give to us ? cat80 = 30 min ? cat 150 = 1 hr ? Do cat150 girl offer 30min session with 80$ ? Recently I tried with a cat150 . I ask for 30 min session with cat 150. OKT says cannot.

cat150 offer 1 shot only in 1 hour ?
