When I was a lad we used to hire a car for holidays (in the UK of course, my brother and I didn't know "abroad" existed back then). Down by Chew Lakes there was a little hexagonal toll house, with a thatched roof, that sat in the middle of a junction. Bristolians and other West Country folk will know it is close to Stanton Drew. My father told us it was occupied by two people. He claimed to have seen two different bicycles parked outside - but never at the same time. He deduced that one person worked day-shifts; the other worked night-shifts. They slept in the same bed but they never met. If, back in those days, they had a steam-powered computer they could have had the same computer connection - even though they never met.
On the other hand my Dad could have been joking. We have an odd sense of humour in my family.
