A commenter notes that Starbucks stores in California are prohibiting smoking outside their stores:
Starting Monday, Starbucks customers are welcome to sit outside and sip a while — as long as they don’t light up. The international coffee giant is extending its ban on indoor smoking to outdoor patios and dining areas in California.
The change was prompted by an increasing number of communities that have enacted smoking prohibitions in outdoor dining areas.
This is their right obviously, though I would have preferred their hand not be forced by excessive regulations. Previous coverage of Starbucks and smoking policies here and here.
