This is not the case for the Un-Caffeinated. This group sleeps through the AM commute both on the commuter trains and the subway.They're bleary eyed. Materials they intended to review lie unattended in their laps while they linger in the previous night. They walk more slowly up the stairs and are more irritable when you hurry them along—or hurry by them. They stroll, they trudge, they linger.
