“Thomas Hobson leased horses, and having noticed that given a real choice his customers tended to pick the same horses over and over again,
leaving them seriously over-used while leaving others almost completely unexercised,
he had customers automatically assigned the one nearest the door rather than let them pick, so all the horses would be used and exercised equally.
The customer’s choice was “Take it (the horse assigned) or leave it (don’t get any horse).”
A Hobson’s choice is a false choice because there’s only one real option if you’re in need of the thing being offered.” (TVtropes)
