Order Up

Order Up is a side quest in Fallout 4 that takes place at Drumlin Diner. Trudy, the owner of the diner, can be heard arguing with Wolfgang over her son Patrick's debt. For all available options, talk to Wolfgang to begin the quest.

Detailed walkthrough
When the Sole Survivor discovers Drumlin Diner, they will hear an argument between Trudy and Wolfgang. The player character can:


 * 1) Enter the diner and talk to Trudy. All conversation options result in her offering money for the player character to kill Wolfgang. The player character can ask for extra, accept or refuse.
 * 2) Talk to Wolfgang. He and Simone will initially draw their weapons, but it is possible to ask what is going on.
 * It is possible to threaten him to lower his gun, then subsequently extort him for money, with a third check to get him to run off entirely. If the intimidation fails at any point, he and Simone will turn hostile. If they are killed, Trudy will reward the player character. Until the third Charisma check, it is possible to ask what's going on, offer help or make a sarcastic remark.

If Wolfgang is not hostile or has not been driven off, he will ask for help, with either talking some sense into Trudy or taking her down.
 * The player character can ask about Trudy. Wolfgang explains how he got her son Patrick hooked on Jet. The player character can agree that they should pay what he owes, that Wolfgang's a scumbag for making him an addict or that they are both in the wrong. The conversation returns to his offer.

The default payout is 100 caps, but the player character can haggle for 125, 150 or as high as 200 (unless they hustled him earlier), to agree to talk to Trudy or join them in the attack, the latter of which turns Trudy and Patrick hostile.

Talking to Trudy after Wolfgang results in her refusing to pay up. The conversation can take one of a few turns:


 * 1) The player character can offer to help her instead, in which case she will offer 100 caps to kill Wolfgang. This can be haggled up to 125, 150 or as high as 200. Refusal to help Trudy turns her hostile.
 * 2) She can also be convinced or threatened to pay up. If the "end peacefully" option fails, the quest defaults to her offer to kill Wolfgang. If the "Threaten" option fails, she will turn hostile. If either option succeeds, the standoff comes to an end.

By this point, talk to whoever is still alive to complete the quest:
 * If Trudy is killed, Wolfgang takes over behind the counter and becomes available as a chems merchant.
 * If Wolfgang is killed or driven off, Trudy remains and becomes available as a general goods merchant.
 * If Trudy is convinced to pay up, she remains behind the counter while Wolfgang leans up against the wall outside. Both become available as merchants.

Bugs

 * If Wolfgang is killed during the "Talk to Wolfgang" objective at quest stage 3000, the objective will not clear, making the quest impossible to complete. The quest can still be failed by killing Trudy and Patrick.
 * If Wolfgang and Simone are killed, their bodies do not disappear. They will appear as they were left, and in the same location. However, checking the bodies several in-game days later, even if they were looted clean and still appear to be naked, will reveal that new loot is back on the bodies. Visited regularly, the bodies can be re-looted several times.
