Taking out the Trash

Taking out the Trash is a radiant side quest in the Fallout 4 add-on Nuka-World.

Detailed walkthrough
The quest involves putting a Shock collar on a raider in the Commonwealth. Nisha will give the specific location that you need to go to.

Collaring a raider can be done by sneaking up on a them and clasping it on them before they can react, or by beating them within an inch of their life, at which point they'll fall down stunned and you're given the option to collar them. For this last method be sure to have your companion to 'stay' at a safe distance or they might help in the fight and kill your raider before you're able to collar them.
