The cost to ride New York’s Metro North Commuter train is rising, along with the Metropolitan Transportation Authority’s cost to ride the subway. In Grand Central Station, Eddy’s shoeshine raised the price of shine from $3 to $4. The beverage cart vendors located outside the train platform in Grand Central raised the cost of a Coors Light (my favorite occasional Friday pleasure for the ride home) from $2 to $2.50. Have you noticed? Price inflation works like dominoes. Of course there are real external inflationary pressures, but caving into to price increases on a local level seems instigated largely by the phenomenon of monkey-see-monkey-do.
