I showed up at the appointed time, and politely waited at the front desk. After a few minutes a lady noticed me, and before I could speak, she said "Oh, glad you're here. Go through the door, and down the hall. It's the 3rd room on the right."
So I obligingly headed that way. I found myself in a room with a few business machines, and no people. An odd place to do a lunch talk, but some offices have very limited space. So I got out my speaker's notes and quietly glanced them over while I waited.
A few people walked by and looked at me, but didn't say anything. Finally the lady who sent me in came back.
Office Lady: "Uh, you can start whenever."
Dr. Grumpy: "But there's no one here yet to give my talk to."
Office Lady: "Talk? What do you mean?"
Dr. Grumpy: "I'm Dr. Grumpy, here to give a talk on Fukitol..."
Office Lady: "Oh, I thought you came to fix the copier."
