A Most Ingenious Paradox

I used a lot more weekend coffee than normal - I took several days off work, plus a couple batches of Irish coffee. I wouldn't be able to make coffee Sunday morning without buying more beans.

So I went out Sunday morning to a neighborhood coffee shop, and bought a pound of coffee beans. That comes with a free drip coffee.

Because I drank the free drip coffee, I did not need to buy the coffee beans to make more coffee.
