On QUIT only triggers after you actually quit.
If you want to script your own custom/ random quit message, your best bet is to place a custom identifier into your Quit Message field under IRC > Messages.
Put this code in your Aliases or Remotes:
Alias QuitMsg {
return $read -n quitmsg.txt
}
Then use
$quitmsg as your Quit Message.
Alternatly, you could simply put
$read -n quitmsg.txt as your Quit Message, too.
