A friend of mine, who was struggling financially at the time and was riding an old Trek 2300, was riding with some friends who all had the latest and greatest high-end bikes. One of them flatted and started pulling out his cell phone. My friend asked what he was doing and he replied "Calling my wife to come get me"! Turns out he didn't carry any repair equipment and had ended his rides whenever he flatted. My friend schooled him right then and there on how to fix his flat.
