When creating your own world remember that people in ours have different ways of doing pretty much everything, as this video by BuzzFeedBlue about coffee shows.
Also remember that depending on the size of your countries/states people within them can have different cultures or variances. In addition to food preferences, dress, and whatnot, there are also linguistic differences: accents, varied speech, some words/phrases used more than others.
And your world won't be static, things will change as time goes by. How does the younger generation see things in contrast to the older generation? Do they want to do things the same way, are they taking on new cultured/rustic habits? Are there heralds or other figures who pass along information, who might also pass along trends?
