How to return observable from subscription
<p>I have a service that returns an observable, items.
So one can use it as myService.items().subscribe().</p>

<p>In another service "service2" I want to create a method that will return an observable, it will call myService and act as a pipe so if one call service2.items().subscribe()
The items first will come from myService items, the items will be manipulated with service2, and the items will stream to subscriber.</p>

<p>Can it be done?
I manage to do so with event emitter, but I understand it is not a best practice to use event emitters in services.</p>
