Port-A-Diner (Fallout 4)

Port-A-Diners are claw style vending machines in Fallout 4 and Fallout 76.

Characteristics

Port-A-Diners will rarely dispense perfectly preserved pies. The chance is extremely low, with even a whole day of game time harboring no results. The machine will not attempt to dispense anything else behind the glass.

When activated once per day, each individual Port-A-Diner will have its own individual chance, allowing the player character to hit all of them individually in order to gain one perfectly preserved pie for any number of machines.

Giving the perfectly preserved pie to a companion will cause them to eat it when injured, consuming the pie. Upon giving it to the chef in Vault 81, she will say "How did you get one of my pies?!" in an on-screen dialogue. This will only be said once, regardless of how many times a new pie is retrieved from the Port-A-Diner.

When activating the Port-A-Diner, if the claw immediately drops down it will result in a failed attempt. Only when the machine is activated and the claw slightly adjusts itself above the pie will it result in a successful attempt.

Notes

When a Port-A-Diner is activated, the game generates a random number between 1 and 1000. If that number is less than or equal to $(2 \times Luck + attempts / 2)$ the pie will be given. By cumulative probabilities, a player character with Luck 5 has roughly a 50% chance of obtaining the pie within 36 attempts, and roughly the remaining chance of obtaining it between 37-125 attempts.
The Port-A-Diner at the Nuka-World junkyard has a 100% chance of giving out a perfectly preserved pie.
There is also a clean version of the Port-A-Diner, which is unused in the game. It can still be found in the game files.

Bugs

PC Playstation 4 Xbox One Sometimes you will not get a pie (Port-A-Diner's container will be empty) even if the mechanical claw successfully took it. This bug appears to be very common in Medford Memorial Hospital.^[verified]
