Its not even really about being hungry. Its about having fun. Even if you're watching at home plenty of people end up paying more money for wings and chips or other shyt you wouldn't eat normally. Thats also a waste of money...you could be eating spaghetti or something and have left overs for the whole week
Nothing wrong with packing picnic baskets or whatever you want to do to save money...if thats what you like. But if you want some nachos and the shyt costs 9 dollars...and you have 9 dollars...fukk it. YOLO and so on.
