I'm not in a cube, I'm in the main office/reception area.
Luckily (unluckily) I have a desk with a raised counter on the front, and if anything is on the counter, it's hard to see me unless you're directly in front of my desk.
At one point, the VP called a director names, and tried to enlist the dealer in badmouthing her and her political choices.
When a visitor off the street came in and my VP didn't interrupt his diatribe, I could have crawled under my desk. It would have been a "spirited debate", if it had been in the break room, not the first point of contact.
