If Bob doesn't like the type of game he's playing, he should find (or make) a new one. If no at the table (DM included) likes the idea that a PC dies under these circumstances, they should find a new game or houserule to prevent that consequence.
Yeah, I agree. I don't have a problem when this happens in 3e; it's part of the game, you know it can happen, you deal with it if it does.
The example is just to show that the DM can be a good DM and that Bob doesn't have to make any stupid choices for him to die.
Then again... when I play I usually get the Rogue or Ranger to move 30 feet ahead, Silently and Stealthily (a level of Barbarian helps for fast movement so you don't slow down the party). In this case he'd have crept up to the crest of the hill and the orc would have to beat his Hide and Move Silently checks. So maybe there was something Bob could have done. Huh.

(I'm imagining the orc encounter is on the random encounter table to show how the orcs in this region of our sandbox are getting more and more blatant in their ability to harass travel; they leave an orc to guard a bridge (maybe there are a few more orcs lounging under the bridge out of the hot sun).)
