like, theoretically someone could have read the full Van Halen rider and thought, damn we're not doing all this stuff but lets do the brown M&M's thing because you know how these touchy, irrational artist types are, if they see one brown M&M they probably lose it!
the point was that the brown m&ms have an important signalling effect? and I said well there could be a case in which the signal you thought you were receiving from the m&ms being present was wrong?
The point is only to detect whether they read enough of the contract to find that buried, arbitrary but highly visible detail, not to ensure they execute everything within it.
