There is no such thing as commonsense within 10 feet of a running aircraft engine. It must be fully trained sense with appropriate control and oversight.
I have seen an experienced dispatcher run out of the gate again when he realised he'd loaded an unaccompanied bag and run round to the captain's window in a blind panic during a four engine start up. Dumb? Yes, but no he wasn't. He was uncommonly smart. Happened? Yes. Was he hurt? Thank Goodness no, and he learned something afterwards.
