Plot hole: In the beginning of the episode, Khan makes Connie's friends sign a contract when they come over for Connie's sleepover. Despite being an intelligent man he should know that even if a child signs a contract, it is null and void unless the child is with a parent or legal guardian. Khan might be rash and strict but with how seriously he takes these contracts it seems doubtful he would forgot something as important as a minor needing an guardian to sign an contract. Evidence of how serious he was about the contract that a little later in the episode, he even takes away the girls pillows when they are fighting in order to avoid anyone getting hurt. Then after this one of the girls makes a comment how Connie's dad made her pay for breakfast.
