When is dinner ready?

Are you as tired as I am of this question? Kids home from camp and I hear this no less than 15 times per kid. for those of you who are math challenged that's 150 times a week during weeknights - 600 times a month - 7200 times a year!! ENOUGH ALREADY! I was thinking I might given them each $5 a week and charge them a dollar for every time they ask me and if they don't ask they can keep the money.
