But what happens if someone gets sick or hurt?  They'd come in to check, right?  Protect their investment.  And there'd only be one or two of them in here.  We could handle that."<br/><br/>She hefted the mug in her hand.  It wasn't much of a weapon, but enough hits with it might still do something.  "Or maybe there's a way to block the door open -- make them think it's locked when it isn't?  Then we could sneak out."
