10 things we learned this week
Wily water companies, McDonald's McAccounting error, Worldpay's whopping IPO.
1. Water companies have been accused of 'withholding' £800m of cost savings from customers. It's almost as if their purpose is to make a profit.
2. When it comes to company accounts, a decimal point can make a big difference.
3. With a £4.8bn valuation, Worldpay is London's biggest IPO this year.
