Map Mix-up on the Seibu-Shinjuku Line

For whatever reason, one of the people who changes the ads in the cars on the Seibu-Shinjuku line goofed and put a station map up for the Seibu-Ikebukuro line instead.

I wonder how many old people freaked out, got off the train and had 20-30 minutes added to their commute.

And how many others simply stayed on the train, pleasantly surprised that the Seibu-Ikebukuro now magically extends to Takadanobaba station?
