Professionally ignore people with style.

You have contacted a person who is currently somewhere else on purpose. I am at an event where every hallway conversation became a calendar liability. If this involves a table, a room, or a complaint, start with the current supervisor. I expect to respond after I drag myself back into operational range. If the issue is urgent, call the venue rather than emailing into the abyss. Thanks for adapting to the mess with suspicious elegance.
