Oh yeah I've been there as well. I've also seen upper management insist on adding more infrastructure monitors on the walls for the same reason: clients think they look cool!
Wow, I remember being a junior guy long ago and getting assigned this task. They brought in two huge (at the time) monitors and had me set them up to show “real time” graphs and plots. Didn’t matter what the data was, just find a computer, plug it into those monitors and show some techinal-looking ambiance for the 15 minutes that some investor or other big shot will be in the room.
