Much like Santa Claus, the Soup Faerie knows all, and can tell how many neopoints you have. However, you can fool the Soup Faerie by making a lowball trade offer for an extremely expensive item at the trading post, or on your own trades before you go to the Soup Kitchen, and then retract your offer after getting the soup and the avatar. You are allowed to visit the Soup Faerie on your side accounts.
