Its a called a "Foodie Call", I think I have been the victim of one a couple of times well maybe more than that. I would name, names but Im not.

Would you go on a date just to get a free meal out of it?According to Social Psychological and Personality Science, they found 23% to 33% of women admitted to engaging in at least one foodie call. That's when a person sets up a date with someone they are not romantically interested in, for the purpose of getting a free meal.

Hold on but that's not it.."They found women who admitted to a "foodie call" also scored high on the "dark triad" of personality traits, which includes narcissism".
