It outrages me that Tartine charges me sales tax on a loaf of bread. I want to lodge a class action lawsuit to bring this place to its knees.
Taxing bread: Tartine [San Francisco, Mission & Sunset]
It could be this application of sales tax is proper. There is some rule they call 80/80 regarding places that sell most of their food for eat-in (which would normally be taxed), and for ease of bookkeeping they just tax everything anyway.
The appropriate State agency is the California Dept. of Tax and Fee Administration, their number for reporting violations is (888) 334-3300.
I think it is not worth battling this windmill, and just find another bakery.
I tried to decipher those regulations when this was posted.
They are complicated.
