McDonald's rounding on pennies? Not lovin' it

McDonald's rounding on pennies? Not lovin' it: If you're a cranky old cash user like me, McDonald's doesn't want your business. Let me clarify: I'm sure McDonald's, despite being the largest fast-food chain by sales in the world, still wants everybody's business, including mine. But the company just announced it will be rounding cash orders to the nearest nickel. Blame the nationwide penny shortage.
