Friendship meal

When a person (usually a female) accepts a dinner "date" from another person (usually a male) only to get a free meal. Often times the person paying for the meal feels like it is a real date, but really its just a friendship meal and the accepting person "only wants to be friends".

Sally accepted a friendship meal from Frank...
Poor Frank thought it was a real date, but Sally was just looking for a free meal and she only wants to be friends!
