Tend to Your Business

Tend To Your Business is a side quest

Detailed walkthrough
After Elder McNamara is ousted and Head Paladin Hardin becomes the new elder, you are given the opportunity to join the Brotherhood of Steel through a heroic act. Hardin already has a task in mind: to wipe out the Van Graffs as a show of loyalty to the Brotherhood.

Methods of Madness
Due to well-equipped guards, and a mandatory pat-down upon entering the Silver Rush (the Van Graff base of operations) killing all of the Van Graffs can be a difficult task. However, there are multiple ways to kill them.


 * Killing Simon the door guard allows the player character to enter the Silver Rush without surrendering their weapons.
 * Weapons can be obtained inside the store through either theft or by buying them.
 * During Birds of a Feather the fourth and final customer will attempt to blow the store up and, if allowed in, will result in the death of all Van Graffs, with the exception of Simon. However, this also results in the destruction of much of the merchandise as well.
 * If the player character completes this quest, Simon will allow the player character in without removing their weapons.
 * Once the first part of Birds of a Feather is completed (the part where the player character acts as a door guard) the player character will be able to enter the Silver Rush without relinquishing their weapons. In addition, they will receive experience and payment from Gloria Van Graff as a reward for completing that section.
 * Alternatively, one could simply complete Birds of a Feather before completing Tend to Your Business. However, only completing the first part of that quest will allow you to continue to have Rose of Sharon Cassidy as a companion.

Conclusion
After eliminating the inhabitants of the Silver Rush, return to the Hidden Valley Bunker. Once there, inform Hardin that the player character has completed his task, and he will reward the player character with full membership into the Brotherhood of Steel, rewarding the player character with a suit of T-45d power armor and helmet (a formal ceremony would apparently be inappropriate). In addition, the player character receives the Power Armor Training perk, if they do not have it yet.

Behind the scenes
The quest name is a reference to a hit song recorded by blues musician James Wayne in 1951.
