Trout fishing with worms

When I was a kid, my father and I would fish for bluegills, sunfish and so
forth with worms. Trout fishing came up, and I asked my father if we could
go trout fishing. He said you could not catch trout with worms. Once I got
"older", I was visiting a private trout hatchery that stocked , I guess,
private streams. The person at the hatchery said that only "jerks" fished
for trout using worms. He implied that using worms to catch trout was really
easy, and no challenge. Now I am confused. My father acted as if you could
not possibly catch trout with worms, and the "expert" acted as if catching
trout with worms was like shooting ducks in your bathtub. Any opinions about
this?

Thanks
