Keeping track of rations
I usually require lower-level parties to set standard operating procedures, such as orders of march and watch, pitching and breaking camp, and feeding/watering steeds. Keeping track of rations and ammunition is part of this. At higher levels, we don't need to role-play out such scenes, and rations only become important when spoiled, stolen, or lost.
It's assumed that each Player Character keeps track of these things, and when they level up, I tend to charge a "mundane provisions" fee of say, 100 gold pieces each when they're in major cities to replace torn clothing, get fresh water/wineskins, and buy new armor straps/belts/sheaths. This doesn't include lodgings, which vary too much, or tithes, guild fees, and taxes, nor does it cover any enchanted items or spell components.
That way, when a midlevel party is ambushed at night, has ridden across a desert, or stumbles into an Elven garden, we can focus on the role-playing or cinematic aspects of their travels.
