I *have* seen groups turn MGS around. We had an AD&D 2e game where MGS player had his character eat a note we knew contained a critical, plot-stopping, clue. Pure MGS, as there was literally no reason for his character to do so. So we (other players) held him down and cut the note out of him. The GM wrote down the note's contents, tore up the note into pieces, got the pieces wet, and handed them to us.
We put the puzzle together, read the clue, and carried forth into the depths of the lair. Without "bob" and his PC.
