Now you're interested.  Who doesn't like a free meal afterall?  Wait until you find out what the  University of St. Andrews in Scotland wasted its research money on.

Researchers found that the likelihood of a woman scoring a free meal on a date depends on her looks. The prettier she is, the more willing a man is to pick up the tab. Unbelievable, but true. But wait, there's more: the study also revealed  that the more attractive the man, the more likely a woman expects him to pay for the date.

So at least for women, attractiveness seems to equal entitlement.  The attitude is that they bring more to the table so to speak.  I'd bet that guys also feel that a more attractive woman is worth spending money on, otherwise, they wouldn't foot the date bill.   Right?
