I can’t talk right now

I am working for country and too many people pick up just to say

I am on conference call

Or

I am at work

Or

I driving

My question WHY TF are you picking up the phone during conference call? Or at work IF you can’t talk?

And WHY are you calling me back just to say ‘please take me off your list’?

I found kick.

When they ask to take them off my list I am saying ‘do you want me to lose my job?’ And while they thinking - I hang up.

So main question is WHY DO YOU PICK UP YOUR PHONE IF YOU CANT TALK?
