I've brought up the "do you really wanna do this?" message on tossing my salvage shell a couple of times. I make it a point to pay attention to any kind of context menu such as that. It's like an emergency DONT TOUCH YOUR KEYBOARD ANYMORE, for me.
Sometimes, to be cute, I'll pearl myself and put my Shell in Mog House (or Satchel, now). I do it to be silly, but you could do it because you are still learning now to FFXI.
