Yep, I remember those. I worked at a service station (not a gas station... there's a difference) from '73 to '81. The first crisis was in '74 and the second was in '79.
I would have liked to see a political cartoon where Detroit is sleeping and the (digital) alarm clock shows "1974", goes off, Detroit hits the snooz button, then the alarm clock shows "1979" goes off, and Detroit hits the snooz button again, but I digress.
I remember starting the day and as we started our opening-the station-chores, a line started forming. By the time we switched the pumps on, the line was quite long. I remember the feeling in the pit of my stomach "another long day" hopefully not too many cranky customers.
At the end of the day, we use to tape a "LAST CUSTOMER" sign on the back of the last car in line to shut things down. You'd ask the customer if you could put the sign on the back of their car, no one ever refused (of course). Anyway, the "last customer" would often get to the pumps, and surprize, surprize, he wasn't the "LAST CUSTOMER" anymore. The sign had migrated back a few cars. We never fussed about it. It was just part of the game.
On the positive side, working at a service station had it's perks, I never had a gas shortage...
