Imagine, if you will... that this mysterious wealthy dude called Duke would really exist in this post apocalyptic world and he would really own many businesses including the legendary casino, which is the mysterious place associated with so many legends and stories, but mostly known for being the place where Duke's casino tokens come from. What if this mysterious wealthy man called Duke one day sat on his expensive couch thinking: "Man, what I would give for a bottle of good old CENSORED-Cola"? Well my friend, this is when it struck him and he came up with an idea of creating his very own post-apocalyptic CENSORED-Cola. But being a good businessman, he knew that if he wants his new drink to sell like hot-cakes, he has to come up with a good catchy name for it that everyone would love and easily remember. He became so obsessed with the idea, that he wanted everyone to feel familiar with the name of his drink even though they never really drank it in their life and that's when he came up with a simple name Duka-Cola. It was not only easy to remember, but also the name had some magic in it that made everyone feel strangely familiar with the drink, even if they never drank it in their life before. Duke immediately gave orders to his employees to start searching for any references, books, leaflets, posters, etc. to get as much information about the original CENSORED-Cola as possible. His main intention was to find the original recipe for CENSORED-Cola everyone used to love before the apocalypse. Once they found everything they needed, he ordered them to burn every proof of existence of CENSORED-Cola's original recipe and build the factory on a remote, undisclosed secret place and start producing his new drink based on the original, so that survivors all around the wasteland could enjoy it.
The legend says that the original Duke's name for his new drink was actually Duke-Cola, but his employees who came mostly from various groups of bandits, raiders, many of which can't properly read and write didn't get the name of the drink right and so it happened that instead of the intended name Duke-Cola, they went with the name Duka-Cola. Of course the regime under Duke's leadership has always been very strict and hard to make sure raiders would respect and obey him all the time and such a mistake could not be tolerated. He found the person responsible for mispelling the name for his new drink and shot him on the spot. But despite this unintentional name change, the new drink Duka-Cola became very popular all around the wasteland.
Just an idea...
