There's a lot of places to go get food, and it doesn't take much to turn you off from going somewhere. McD's is on my shortlist of 'never again', along with Applebees and a couple others, due to a string of bad experiences. I don't need that. I'm willing to take my money elsewhere.
If 15/hr gets better service without raising the price of food, I might reconsider McD's, but I have to think something will get cut if employee costs go up.
Of course it will! You don't raise expenses without it being passed to the consumer. You either reduce expenses elsewhere, like inplimenting. Kiosk ordering system reducing 1/3 of your staff, reduce the quality of the product, which is already borderline to begin with, or raise prices. Or all of the above!
Unfortunately, convenience keeps me from being able to start my own never again list. And I suppose that is part of what they are banking on.
