Professionally ignore people with style.

The timing of your email is spectacularly unfortunate for both of us. I am on a break and treating my email like a distant rumor. If a guest says it is definitely an emergency, please verify that with an adult. A delayed answer is forthcoming once timing becomes less ridiculous. If the issue is urgent, call the venue rather than emailing into the abyss. I appreciate your understanding, especially if it arrived late.
