Receptionist: Yes, he is, but you can't see him right now because he's in some kind of meeting about the African school thing... can you leave your details?
Cue several minutes of me trying to explain that this was in fact the meeting I was meant to go to, her refusing to go and confirm with the people in the meeting that I was indeed meant to be there, and my eventually being asked to leave as I was holding up the queue (that consisted of about two people).
I mean, wtf?
