Pulling out the trusty decompiler, here’s how checking the trash works:
- It only affects an NPC within 7 tiles of you.
- …unless that NPC is Linus; he doesn’t care if you dig in the trash.
- The NPC will give one of three disgusted responses.
- You lose 25 friendship points (10% of a heart level) with that NPC.
- You may get a random item. (It appears that better luck that day gives you a better item.)
