Honest question: Do the cafe workers get paid the same hourly wage as the bookstore employees, or are they classified as restaurant personnel and make $2.13/ho

Honest question: Do the cafe workers get paid the same hourly wage as the bookstore employees, or are they classified as restaurant personnel and make $2.13/hour + tips like I did when working in a restaurant / cafe setting? Does SF/CA have different rules in place? I'm genuinely curious and some brief searching alludes to the $2.13 going up to $7.07. That's not $15/hour. It's interesting to use the "prices go up everywhere" argument when not directly addressing the economics. IMO the $2.13 isn't really a viable discussion point for business owners. Tips are the accounting and tax responsibility of the employee / earner...hmmm...
