As a note, in Cali they will get paid a normal minimum wage ($10/hr I think) . The state does not make an exception for tipped workers.

This might well create a blurred line on how one should tip. Should it be more the EU (and ROW) model, and not the US model?

In TX, they probably make the US required $2.14/hr.

It has been debated if the CA model actually hurts the workers. They get more in wages, but hurts them on tips.
