My boss recently scheduled a meeting between them and myself so that I could teach them exactly how to use the backend editor for the trading arm of our company. I arrived at the meeting on time with the website already loaded on my laptop. My boss wasn’t there so I waited.

My boss didn’t show.

Client: (a few days later) What happened? I was waiting around for you all morning!

Me: I’m sorry for the miscommunication, but our meeting was scheduled for Wednesday. I didn’t know you were expecting me today.

Client: Wednesday? No, I rescheduled the meeting for this morning.

Me: No one told me that was the case.

Client: I changed the booking in my diary. I heard that you IT people could see that stuff.

My magic IT powers don’t extend to paper diaries, no.
