Server admin: "When do I need to make this config change for you?"

Me (in my head): "You mean the one I put a note in the change request ticket about in ALL CAPS and surrounded by asterisks saying 3pm (aside from the scheduled time field that the ticket requires), and the one we then subsequently chatted about where I reiterated the criticality of the timing about and the one I copied you in the email chain about that said the time in big, bold letters the time? THAT config change?!"

Me (IRL): "3pm, please."

(does not inspire confidence, though better to be asked then they just go off and do it whenever the mood strikes I suppose, which HAS happened)
