While most subway lines/systems are intuitive, coming from anywhere far away where a different language, logic and system is used can be intimidating, particularly for Rick's target crowd. Plus its annoying for those standing behind clueless tourists (i've been one more than once) who have no idea how to buy a ticket.

While I too would rather gouge my eyes out than waking up at the crack of dawn, but for many its a valuable service..
