"Absolutely, under no circumstance at all are customers allowed to play Stairway to Heaven, Sweet Child of Mine, or Smoke on the Water while trying out guitars. Thank You."

This is a sign I found on Wikipedia. It was apparently photographed in a window in Denmark Street in London.

Denmark Street is where most of the London music shops can be found.

I will be sure to take note next time I buy a guitar in London (Lois bought her Tanglewood guitar in Denmark Street).

Well, at least we can still play "Wild Thing" and "Smells Like Teen Spirits".

Wasn’t there a similar sign in Wayne’s World?
