In reply to Richard Ginn.

Probably some old POS system that doesn't support custom named taxes or something is my guess. I can't imagine that they've added a tax that just goes into their pocket, so it's likely something more local that they're "adding" as a tax to the bill.

That's unlikely to work in California, having lived there for years I can tell you the state goes through great effort to disguise how much taxes raise the price of something, so for a lot of things that tax has to be built into the price of the item you're not allowed to itemize it as a separate charge.
