I work as an architectural draftsman. Once I made a concept for a house. I send it to the client as PDF via e-mail so that he could review it and make changes. Instead of making the changes directly in the PDF or print it, scribble the changes on it with a pen, scan it and send it back via e-mail, he calls me:
Client: There are some changes that I want you to do in the draft. Some walls need to be moved. Starting with this wall.
Over the phone, I heard an audible tap on a piece of paper.
Me: Sure, no problem. I can do that, but can you be more specific about which wall you mean?
Client: This wall right here!
Once again, I heard him tap on the paper.
Me: I’m sorry, but I don’t know which one you mean because…
Client: (cuts me off) If you go from the living room to the kitchen and then to the next room, that wall there!
At this point, the tap on the paper is angrier.
Me: Sorry, but I can’t see which wall you’re pointing at.
Client: (shouts) WHY NOT? CAN YOU MOVE THAT WALL NOW OR NOT?
