Yes its really funny.
I bought recently a S.psittacina from a local store.
She told me that it should have shaded light with lots of humidity.
I told her that it doesnt need that high humidity.And can be grown in full sunlight
She just like "nooo..really?" like I was stupid.
I said yes I have about 60 more of Cps at home.
Then she shut her mouth and started with the next customer
