My last DM generally didn't micromanage my elven ranger's arrow supply until I got magically enhanced arrows. He's never been a stickler about trail rations, either. He calls it "dungeons and accounting" to worry about whether you have food or not, and generally made sure to strongly suggest that we camp (and eat) somewhere every night, or if in the city, go to an inn for a meal.
When I started with this DM, however, before I knew any better about his style, I had just bought a 3E PHB and was reading it cover to cover, so I didn't know you DIDN'T have to worry about ammo usage, or encumbrance, or food supply. I kept pretty good track of that stuff as a result, and until my ranger sought out and acquired a bag of holding, I either dropped the pack to begin fighting, or never moved more than 20' per turn. And my first order of business out of combat was to refill my quiver, so I'd be ready the next time.
Of course, with a ranger at, by now, 11th level, even a bad roll on a Wilderness Lore check generally allowed us to gather enough food every night, and my PC did it so often that by the end of White Plume Mountain, when we ventured outside, we didn't even bother to go through the motions.
