Retrieving ammunition is one of those things that is, imo, similar to taking piss breaks. Like yeah, of course your character is doing it, you don’t need to track or talk about it. The only time it will ever come up is if there’s a reason it’s noteworthy. Like if you get ambushed by a dragon immediately after the fight. Okay, you lose some of your arrows because you don’t have time to pick them back up before hauling ass out of there.

Similarly, I’ve found that tracking rations and water supplies and such is usually a waste of time. If there’s a plot reason those would be serious challenges, like you’re trapped in the middle of the desert, then of course we’re going to need to get into the little details of how you’re getting food and water every day. But if you’re traveling through reasonably well populated countryside and haven’t gone more than a couple days without meeting people, you’ve got food. Even the most curmudgeonly old destitute farmer isn’t going to send a band of travelers down Completely Unpopulated Road without enough food to reach the next hub of civilization.
