Professionally ignore people with style.

This automated reply confirms I am unavailable, as previously implied by my calendar. I am on leave for burnout recovery and refusing to romanticize exhaustion. If this involves a table, a room, or a complaint, start with the current supervisor. A delayed answer is forthcoming once timing becomes less ridiculous. If this cannot wait, the on-shift manager is your best bet. Thank you for adjusting to this entirely foreseeable delay.
