Oh man, early Slack was great. Back in ~2015 or so I submitted a ticket about something trivial (why I could no longer hide the menubar or something, I forget), but just for fun I did it all in stilted archaic language like you'd see in the 1600s or something. "Behold, in days of yore when the Users of the Land sought refuge from the tiresome typing that had so bedeviled their lives hitherto..." etc. Anyway, their CS team responded in kind. Hands-down the most fun I've ever had with a support ticket.
