Often times in when alchemy is thought of, we think medieval times with wizards and sorcerers. What if such things existed in modern days such as today? What if the focus of alchemy is common knowledge is can be used for favorite drinks? What if you have a soda machine that can create soda with special properties? The varieties is endless, though good taste is limited. What kind of concoctions can you create?
Historicly, we have had plenty of rl groups like the Taliban and the Puritans who supressed anything which was in any way fun. What if there was some group that was the opposite? (which in time would cause problems of it's own for the civilians under their control.)
