I had a Genie summon some Chill Con Carne in time for when a couple's four children returned from school, in which two of them brought a friend home. I then called the entire family to the food (cancelling the action on said Genie since he didn't need it) and...
Upon finishing the meal, one of the six children set a bar stool on fire! Now, this would be fine to put out, except she set herself on fire in the process and the stool she set fire to was being used by another child; ouch, that's two children on fire. Luckily, an adult had the Brave trait and put the guest child out while the other ran towards the shower.
In short, be prepared to have a Brave adult in the house at all times. I personally blame my genie for that result.
