At the Athens games, people wearing logoed t-shirts were asked to remove them or turn them inside-out before entering the stadia. Nothing says "incorruptible international competition" like a bunch of bullshit rules about what your t-shirt is allowed to say and whether an elevator can display its manufacturer's mark. Ignore That Logo Under the Tape! (Thanks, Marilyn!)
7 To ensure that only the companies that pay millions of dollars to be official Olympic sponsors enjoy the benefits of exposure in Olympic venues, organizers have covered the trademarks of nonsponsors with thousands of little swatches of tape.
In media centers, dormitories and arena bathrooms, pieces of tape cover logos of fire extinguishers, light switches, thermostats, bedroom night tables, soap dispensers and urinals. The Taiden Industrial translation headsets in a large conference room have had their logos covered, as have the American Standard faucets in the bathrooms nearby, and the ThyssenKrupp escalators down the hall.
