There's an opposite school of thought taken by many of my fellow engineers... that the horn is our only defense, and whistle bans should be done away with, etc. etc. Me? I'll just do what the timetable says... either way, I'm all over that horn the second I see anyone come out in front of me, anyway. If some unfortunate soul should choose not to move out of the way - well suddenly the bosses will start asking - why weren't you blowing the whistle???
hey there guy
