One way I shall get back at the fastfood industry for contributing to my premature death from cholesterol poisoning is by waiting for them to assume I want the medium-sized drink with my to-go, then asking for a large after they've rung me up, and relying on their laziness not to charge me the difference. Yesterday it was at Rubio's, and today another 18ยข at Chipotle. Tomorrow, the world?
