If I throw a party at Chuck E Cheese for my 6 y/o and 7 of her friends, am I responsible for feeding the parents, too?

Long story short - a Chuck E Cheese party includes drink, food, and tokens for all the kids. Because the kids are still kind of young (5/6), if their parents come, should I provide them with food? via /r/Parenting http://ift.tt/2kqQxoQ
