Reading the Sebastopol Municipal code is great fun!
I'm not sure it is a good idea to pick through the laws in order to discredit the lifestyle of your political opponents (in part because then they can do the same to you :-/ But I was amused to find that Chapter 5.12 'Prohibiting the practice of fortune telling and other similar occupations.'
It pretty much covers the lot, prohibiting prophecy, crystal gazing, and cards...
This would appear to cover the tarot readings in front of Infusions.
