As mentioned, the BJ80 is probably a code that Les Schwab uses. Google maps is useful, but only Les Schwab can answer that question. Les Schwab has a great reputation, particularly for tires and brakes, but if you trust your dealer, or want to, get a price quote from them too, and compare.
Probably just a quick job operation code in their management system software for a basic brake job ... did they do a brake inspection?
