Fallout 3 random encounters

Throughout the world of Fallout 3, you can encounter random events in the Wastelands. There are certain places where random encounters can happen, but once "activated", a random encounter in a particular area won't change.

You can save outside the spawning area and keep reloading if you don't get the encounter you want.

=Wastelanders, Scavengers, Slavers, Beggers, and Uncle Leo.=
 * A Wasteland Doctor.
 * A Wasteland Junkie.
 * A Scavenger with one or more of the following pets: a Brahmin, Dog or trained Yao Guai. He'll offer you a Nuka-Cola Quantum.  You can barter with him into reducing the price.
 * Two Wasteland Settlers and two Escaped Slaves fighting over a refrigerator of 10 Purified Water.
 * Two Wastelanders pondering an Enclave Eyebot that hovers around them consistently (as opposed to a long patrol like most).
 * Three Hunters.
 * A lone Hunter selling meat.
 * A Wasteland Merchant. After having a talk with him about the Great One, he'll collapse and die.  You'll find a Wasteland Merchant Note on his body about him going to Oasis the next day.
 * Uncle Leo, a friendly Super Mutant. If you tell him you're going to rob him, he'll give you a Dirty Pre-War Businesswear as a present. If you attack him he'll run away instead of fighting.
 * A Scavenger with his malfunctioned Mister Handy. If you repair it, the Scavenger will give you two Energy Cells.
 * Ghoul Wastelanders around a burning barrel.
 * Three Slavers with three Slaves.
 * A man named Ben Canning. He asks for purified water.
 * A Wastelander killing and looting a molerat (only after completing the Wasteland Survival Guide quest). He has different dialogue options, depending on whether or not the player completed all bonus objectives given by  Moira. If the player says he has helped with the book, a congratulatory or a mocking response is received. If the player says he has never heard of the guide, the Wastelander will provide him with a copy of the book.
 * Two Hunters attacking a Giant Worker Ant.
 * Three Hunters attacking a Vicious Dog.
 * A Deathclaw and a dead Wastelander. You can find Deathclaw Gauntlet schematics for the Deathclaw Gauntlet on the dead Wastelander.

 * Mel, a modern Highwayman who will demand caps and items from you. You can either utilize speech options, or kill him.
 * Laszlo Radford (He's hostile and will open fire on you with his Railway Rifle).
 * Sam Warrick shooting at a Wastelander (if he kills the Wastelander, he'll turn on you).
 * Five Raiders, four beating the fifth one from all sides, in turns. It seems to be an initiation.
 * Three Raiders and a Wastelander with a time-bomb on him. You can disarm the time-bomb if you have a high enough explosives skill.
 * Three Wastelanders with info about Oasis. If you ask them about it they'll turn hostile.
 * A Scavenger and his dog or Yao Guai fighting a Protectron, Robobrain or Super Mutant. If you go near the Protectron/Robobrain/Super Mutant after you kill it and the Scavenger is still alive, he'll attack you.  Oddly enough, if you kill him, it results in negative karma.
