Beef
A single bid is a purchase waiting to happen. Two people trading the lead all afternoon is a fight, and every round they add pushes the close further out.
No fights yet.
One starts the moment somebody bids back after being outbid, and neither of them stops. A bid inside the last 2 minutes pushes the close 2 minutes further out, so a fight ends when one of them walks away rather than when the clock says so.
