If you're a man who's scored a date with a beautiful woman, don't let your ego get too out of control; there's a chance she's just after a free meal. That's according to the results of two new surveys, both of which reveal one out of three single women goes out on dates only to be wined and dined. Conducted by researchers at Azusa Pacific University and UC Merced, researchers asked women if they're ever guilty of engaging in "foodie calls." Approximately 33 percent admitted to doing so. Researchers also found the same women who answered "yes" to the question also displayed higher-than-normal narcissistic personality traits. Have you ever accepted a date for a free meal? What are some other reasons to date someone you're not romantically interested in?
