Zach's post about TSA's latest experiments in crowd control reminds me that the other day, while flying through Denver, I noticed that the plastic bins put out by the screening machines to hold our shoes, cell phones, soft-sided bags, etc., were emblazoned on the bottom with advertisements for an online retailer.

We have internally debated the merits of allowing all public buildings, facilities and plastic bins to become advertising opportunities. Personally, I'm against it, although I know this is a losing argument.

But do even fans of the idea believe that people unloading their change and belts into these plastic bins will either A) take serious note of the product and its pitch or B) look favorably on a company that it hears about in this particular context?
