I feel like this is the logical conclusion of a living wage.
If we pay everyone enough to make a living wage, then it should cost the same for me to grab my own menu, utensils and water bottles as it would for a server to do so.
Honestly, the high cost of renting in SF has already made the "move to California and bus tables to get by while auditioning for movie / working on startup" dream impossible. This is just a side effect of the bureaucracy and housing policies here.
