My worst fear when placing orders for work.

Don't I know it as an E/F rider. The worst is when the delay starts after I'm on the train. When I see the notification on my way to transferring to the E I usually just reroute and take the LIRR into queens. I've been averaging about two rides per paper ticket cause they conducted doesn't always come around before I get off. So at least it's not too much of an expense. But still annoying.
