Many years ago one Saturday morning I happened upon a juggling shop. I could already do three balls so I asked if I could try the clubs. After about an hour of failing the shop owner said something like "some people never get it". So of course I bought a set. After 12 hours that day and 12 hours the next I got the hang of it. They are harder to learn than balls but still doable for an unsporty person like me. And, as you say, very satisfying.
That shop owner was a good salesman.
Where is juggling shop a thing?
It was in the UK in 1993, about the time the web was starting to take off. As the other commenter says, there was a much wider variety of shops then.
I am not the person you're asking, but they were a thing in The Netherlands at least. Not super common, but they did exist. Typically they sold other related things too, like diabolos, flower sticks, etc. This was a while ago, before Amazon, when there were just a lot more different types of shops. I am not sure they still still exist.
