They’ve been the most vocal opponent to $15 minimum wage increase in New York, which I’ve always found odd, since they’d be the ones to most benefit from it via competitive advantage, as you said, due to economies of scale. They’ve been making threats the entire time “We’ll replace cashier with computers! If you raise the wage, we’ll totally do it, you’ll see!” and I’m like “Dude, if you had the capability to do it, you gonna do it either way anyway, why you extorting us?”
I guess the smaller competitor restaurants will need to get kiosks as well. They can’t develop their own in-house technology like the big chains do, but they can still purchase 3rd-party ready solutions, like all of them have already done with online ordering. Slightly more expensive to use 3rd party, but that’s economies of scale for ya.
