Tend to Your Business

Tend To Your Business is a side quest in Fallout: New Vegas.

Quest Details
Upon ousting Elder McNamara and placing Head Paladin Hardin as new Elder, he will order the player to kill the Van Graffs to prove his or her loyalty to the Brotherhood.

Strategies

 * The easiest method of completing this task without actually "getting your hands dirty" is to begin the quest Birds of a Feather by asking Gloria Van Graff if she has any work for you. She will assign you work as a door guard first. During your duty, the fourth 'Gambler' to approach the door will say that he wants to replace his revolver. Let him in, saying that, since he declared his weapon, he's good to go. He is actually a suicide bomber, and will kill everyone inside the Silver Rush if you let him in.


 * In the conclusion of the quest Birds of a Feather, if you are willing to sacrifice Cass (by letting Jean-Baptiste Cutting execute her), you may kill a portion of them during the botched arms deal with the Legion (during this ordeal, you might also be forced to kill NCR soldiers). Then, go back and kill the remaining Van Graffs.


 * With a suppressor-modded sniper rifle, find an area where you are "hidden" while sneaking, and shoot the Van Graff guards one-by-one. Attacking any named character in this manner will stir everyone's attention and be hostile toward you, so it is advisable to kill the guards one by one and leave the Van Graffs and Simon last.


 * It is possible to draw most of the Van Graff guards out into the street. Kill the Silver Rush Crier first, then kill Simon soon after since he will also turn hostile. A handful of Van Graff guards will emerge out from the door, equipped with plasma rifles and combat armor. Explosive-based weapons are ideal here, since they will be clustered together as they exit out of the store. Once they are all taken care of, enter the store surreptitiously (attained by using a Stealth boy and crouching, or having a high Sneak skill) and throw grenades from either your arsenal or the ones from the store (which can be stolen). The remaining people inside, consisting of an armed guard and the Van Graffs, will be taken by surprise.
 * It is also possible to draw the guards into the Lucky 38 (so long as the player has access to it) for the Securitrons to kill, but as of the latest patch, this is no longer possible.


 * Using a Stealth boy (outside of Silver Rush), sneak into the building undetected and reverse-pickpocket frag grenades on Gloria and Jean-Baptiste Cutting. This should prevent a messy battle against all of the guards in the room. If the Stealth boy wears off, the player can re-activate one in the building's stairs area.


 * The blast shields inside the store can provide good cover for the player against heavy fire. Companions placed behind the blast shield can also draw their attention, but may be knocked unconscious (or killed) quicker than usual. There is also a "dead spot" behind the pool tables where you can sit and hide. The pool table will provide you a barrier against incoming fire when you have drawn all of their attention.


 * If you Murder the Silver Rush Crier and the Guard out front, you can sneak and use an energy weapon (provided you have the Meltdown Perk) which will get you a Sneak attack critical on all the guards that come out, generally killing them instantly.


 * It is also possible to use their weapons against them. By picking up the mines, grenades and heavy energy weapons on the shelves (using the pick up item key rather than the add to inventory key), it is possible to move items into the shop's toilets where you can steal them out of sight. The plasma mines are particularly useful, as they can be used to mine the approach to the toilets, where it is far easier to defend yourself since guards will have to enter one at a time.


 * If not willing to take a strategic approach, the player can always rush in kill them all, so long as the player is at an appropriate level and carrying a very lethal weapon (Anti-materiel rifle, YCS/186, etc.) that cater to their abilities. Since much of them are wearing armor, having Armor Piercing rounds work very well.
