Many points are not right in place here.
Most Thi women are not from people of book.
Even if that is taken out of scenario, then the intention itself is not correct.
Sahabas RAA did not do Muttah in this kind of setting.
Why it is not cheating when his intention was to cheat???
There will not be an understanding in these women to follow the rules such as iddat or whatever. The man is not making sure of it either.
In your scenario, man goes, does the deed, pays before or after and leaves.
Not a Muttah!
So, neither man nor woman is following what is callled Muttah in this example.
