Corrected entry: In this episode, kids buy things, such as drinks of water, for a certain number of Monstickers. For instance, you have to pay 2 stickers to enter the door. It costs 3 stickers to play on Old Rusty. At these "outrageous rates," kids should burn through at least a pack and a half in a week. At this rate, I would think the parents would get suspicious that they "put so many stickers on their notebooks," and tell them not to go through them so fast, or stop buying them altogether. While it could be argued that the kids have their own money, it makes no sense because they wouldn't have as much money left and would have to ask for more.
