Last night I remembered I needed to call a French Consulate, but it was already 7PM so I figured too late for Boston. So I called the consulate in San Francisco as still business hours there. And got what I needed.
When it's after business hours on the East Coast, you can still find people in their offices in other parts of the country (such as, Federal agencies, department stores, real airport ticket offices, etc.) Even called Hawaii once because too late for California office hours.
Feel really smart when I think to do that. Maybe everyone on the East Coast does?
