Professionally ignore people with style.

I am unavailable and gently surprised this required confirmation. I am at a conference collecting badges, lanyards, and secondhand jargon. Any request involving a discount, rush fee waiver, or vague miracle should wait. I will respond when I return, which is earlier than some expectations deserve. If this cannot wait, use the pre-arranged urgent route rather than hopeful emailing. Thank you for respecting the concept of unavailable.
