Table top players realize a single die roll can change a good/bad situation instantly. When a DM has multiple rolls it being used to create tension like the Nettie situation. If the tension isn't there, multiple rolls are being used because a DM wanted a different outcome but the player either rolled too good or too poorly. Never let something really important be decided by the dice alone. Meaning, a DM shouldn't let something occur in which only the dice can get a player out of. The player needs to make several mistakes on their own and perhaps that one last die roll determines their fate.
