Why Bosses say " Ask everything to me even if you know the answer" when I start working for a new company?

I've been working for 15 years at various Companies.

Type 1 Boss -Whenever I start working for a new company, The Boss says :

" Ask everything to me even if you know the answer"

Type 2 Boss - In an another company

The Boss told me :

" You are not authorized to do anything."

Then I said " OK" And I began to ask everything including the things that I already knew to him - just as he requested.

Then we had a meeting and he critised me for asking for every detail. Then I was fired.

For the Boss type 2 " I did not do anything on my own" because I wasn't given any authority from beginning.. Then I was fired as well.

I find it difficult to hold a job in these conditions.

What should I do?
