I don't think any of us really mind too much if someone wants to jog an elbow now & then (hey guys,did you know about this?)- better than keeping schtoom and getting a smoky hole, but you're quite right otherwise. Maybe we out to try ambling into the Finance dept make a fuss about the seat/mile profit margin or something...everybody else always seems to know just how you ought to fix it -until one day you step back & offer the pen - (oh, sorry, no licence? oh dear, never mind, shouldn't take long...)
Been there (Blacksheep, see email) done that.
