I really hope that amount of food required for Long Rest will be adjustable in difficiulty settings, with option to set it to 0 if people want to ...
I get you, its not question of how long, or how often you actualy need to "search for food" ... its more that the fact you need is anoying.

About trash items ...
Do you know that you can quite easly let them lay just where they are and final difference between your funds if you would pick them would be aproximately 15g per dungeon run? Meaning completely irellevant?
I mean this is problem that resolve itself, as long as you start to act the way you want to. O_o
Since you are using DM example ... imagine it from other way around:
DM: You entered a room.
Player: What do we see?
DM: Nothing significant, imagine it anyway you wish.
Pretty lame, if you ask me.
