Poppycock

 is random encounter mission in Red Dead Redemption.

Story
Mr. Tollets has a package he needs delivering.

Walkthrough

 * Meet up with the Stranger, Mr. Tollets, in Chuparosa. He will tell you to get a package at Nosalida.
 * Once at Nosalida (note: This is a gang hideout so the town may be inhabited by a lot of bandits) go to the docks and open a chest, which contains some money and the package.
 * Next you will have to go to El Matadero and give the package to the foreman. The foreman will give you $1000 to take back to Mr. Tollets.
 * Return to Chuparosa to deliver the cash. A small cutscene will play, and afterwards you will be prompted to either give Mr. Tollets the $1000 or take it for yourself. Note that you must kill him to keep the money; if you do not kill him and walk away with the money the quest will fail. Keeping the money nets you fame and negative honor while giving him the money will give you fame and positive honor.

Note: It is possible to keep the $1000 and get positive honor. When prompted to either give the money back or kill Mr. Tollets, give it to him, then equip the bandana and kill him. Killing Mr. Tollets with the bandanna on will not give you any negative honor, but you will get a bounty on your head, so loot him for the thousand bucks (and some change) and get out of town!

Note: There is also another way. If you give him the $1000 and let him leave the building, follow him outside (Bandana attached, just in case you do need to take care of him yourself) and aim your weapon at him. He will start firing, take cover and allow the lawmen to take him down. Then loot his body, no negative honor and you get to keep the $1000.

A 3rd option is also available. Give him the $1000 and you will get your fame and positive honor. Then follow him outside of the building. Then lasso him and tie him up and carry him out of Chuparosa. Set him down out of sight and slit his throat. Loot the body and claim your $1000 with no negative honor.
