If you work in a restaurant with a lot of kids with dolls or puppets, it’s a great way to have fun. Imagine that you it’s a voodoo doll so everything the kid does, acts on you. If he stabs with a knife, you pretend having pain. If he kisses, you stroke away the kiss. (or rubb it in). If he tickles, you laugh. First they don’t see the interaction, but as soon as they see it, the fun and hilarity at the table is great! Greatly visualized in this ad of an Dutch insurance company!
