I saw this advertisement on the crosstown L train in Manhattan last week and I thought that maybe it was a bit misleading, because I read that almost 80% of New Yorkers don't own cars (I can't remember the source, but it was probably New York Magazine.); therefore, it seems to me that it would have been better for the advertisement to encourage people to get off one or two stops ahead of their normal subway stop and walk the additional blocks.
there's a Lunch Hour NYC exhibit at the New York Public Library (Stephen A. Schwarzman Building, Gottesman Exhibition Hall) that mentions that prior to the 19th century, lunch hours didn't exist in New York City and that most people had a snack for "lunch", so maybe the advertisement should discourage people from having lunch and encourage them to have a snack (e.g. a banana) instead.
But I have to commend that advertisement for encouraging people to take the stairs - at least take the stairs down people.
