Given the previous reactions to any sort of move by fast food chains toward anything like automation, I can't imagine this won't be picked up as fodder for the "look what happens when you ask for a living wage" contingent.
I will always vote for raising the minimum wage but at the same time I know it probably makes automation more attractive.
But while I agree there is an impact, I also don't think we should avoid automation simply to have someone doing a mindless job if it could effectively be automated. People don't necessarily need jobs, they need the resources that having a job allows them access to.
