Cups to bring them back for free refills. We are Stubbs members so we pay $40 a month to see all the movies we want for 2 of us, buy large popcorn most times, go at least 2-3 times a month to the movies, but we sneak in our old cups and get free drinks every time. It’s wrong I know, but it’s our little rebellious date night thing and it turns my wife on so I keep doing it with good results so far.
