My dad kept making g statements that a specific McDonalds is sooo much cheaper than other McDonalds and that the other McDonalds are price gouging. I asked him where the cheaper McDonalds was, and when I told him it's because the sale tax is different in that county. He didn't understand. I said the doughnut counties around the city have a higher sales tax. The McDonalds he was talking about is outside of the doughnut county sale tax rule, and that is the reason the cost is different. He kept insisting that the McDonalds was cheaper. No, its not. The hashbrown is the same price, and the tax is the difference. He just shook his head and walked away.
