I should not see these things together

Adhesive wall posters, Granville SkyTrain station, Vancouver, BC

Why do the people responsible for advertisements in the SkyTrain system keep breaking one of the fundamental rules of advertising,. Don't put advertisements for competing products next to one another.

But what did I see when I walked down to the lower level of the Granville SkyTrain station last week? Advertisements for both Douglas College and Simon Fraser University.

Either one or both schools should get a free "make-up" advertisement as compensation for this mistake.
