What if there are no others around?

Not sure. I might have asked him, and don't
remember. He died of cancer a couple years ago,
and is no longer available for questions.

As to me, I had a lot of trouble at a bank,
which had red and green lights (horizontal)
over the drive up teller lanes.

There is a rule about the order of horizontal lights -- the red is
always on one end -- but I don't know what it is.
