There's a company in my town, hiring devs for a fully robotic kitchen setup. Ingredients are deposited, machines cook meals. A single person can take care of the joint. You can replace a $100k/month bill on personel for a mid-size fast-food outlet with $10k/month for a few guys helping the machine. No strikes, overwork, just ingredients, meals and a bit of maintenance.
Imagine, you are a 50 joint franchise, that's a whopping 50 mil per year in savings (and few hundred people desperately looking for jobs).
