Here’s an idea that’s long overdue. Separate travelers according to speed getting through security checks at the airport. Longs lines at security are like car traffic on the roads. One person’s mistake/delay creates backups all the way through the line. This is attempt to give fast travelers priority access to fast lanes.
In the likely event you had a great idea killed by a client (or an account director), take a look at the “Killed Ideas” contest. Curator and self-proclaimed iconoclast Steve Hall
from AdRants will pick the best to appear in a new Blurb book Killed Ideas Volume 1.
