Why do you have to pay for refill on your coffee you belong to a groub of men who meet once a week for coffee an small talk when you can go to a mcdonalds an get all the free coffe you want you guess?

Because McDonalds knows how to please people, and figures that a group of people who come back for free refills of coffee is a profit, and produces happy people who are willing to come back. Dinners only think of making the profit, and don't care if you come back, cause more people will be coming later. That's my guess.
