Usually their responses to those advances are just a polite hi/thank you and then move on.  There are so many actors/producers/photographers/guys with fast cars promised them the moon but don't really deliver.

Even those who are among the richest in US are not necessary generous.  Too often they prefer to use their positions of power to get freebies or pay the minimum.  It is like a power trip for them.  Besides, some of them are possessive and obsessive which often countered the interest of the women.

Beautiful women who are in need of money fast usually do this by way of hush-hush madams through other beautiful female acquiances.  There are also some who knew the gentlemen long enough to know that the offers are genuine and would last for awhile.  Otherwise, it is extremely hard for them to break that psychological barrier.
