Any mundane practices that are associated with this deity?
Um, YES. As I’ve noted in several other posts in this series, Caffeina has a remarkably strong secular following. Coffee shops. Songs. Bumper stickers. Greeting cards. Ornaments. Coffee Fest. And of course, coffee mugs, coffee mugs, and even coffee cups.
And of course, whenever one or more people raise a mug to their lips and give thanks, it is to Caffeina they pray.
