Profitability begins with the Financial Arrangement and ends with increasing account receivables, sending statements, then resending again with scary 'Past Due" messages stamped on it with red ink made from a single drop of blood from your CPA, collection agencies, bad debt, negative cash flow, and high overhead. The Financial Arrangement at McDonald's begins with clear prices so you can decide exactly what you want to order, and then you pay in full or you will not get your Happy Meal with McVodka. If Doc Ronald McDonald did give it to you first, and you never did pay for it, assuming they had average dental overhead of two-thirds, then they would have had to buy the all natural ingredients, which I assume was the human hair, from the profit dollars of two previous sales. This is why financial arrangement impacts profitability more than price. If you want to boost profitability i'm lovin' McDonald's order, pay, food. If you prefer lovin' the Profit Hamburgler use Dentistry's order, food, and pray.
