Friedman is wrong

There is free lunch. Roughly 3 times a week I have lunch at the Hare-Krishna stall. They park near SOAS and offer their vegan food for free. There is no need to talk nor to listen to their lessons. The food is ok. Mainly carbs and, sometimes, I have to eat real food soon afterwards. But a back of the envelope sum says that I've saved about 400 pounds in year. BTW, I am not the only bloke that relied on Hare-Krishna's services.
