Unless someone on senior staff requests my presence at Noon, I'm responding to your lunch-time meeting request in one of three ways.
A. "What are we having?
B. "Where are we going?"
C. Decline
I'm sure your meeting is very important to you but your meeting is not more important than my need for a sandwich. There's a reason why people's calendars show them available during that time -- they expect to be eating and not meeting.
This is just a note from your friendly neighborhood Mister JT.
