When I read the title of this post, I expected it to be a complaint about flight attendants talking to each other non-stop vs. talking with passengers.
For me, there is nothing quite as annoying as drink service being delayed while the flight attendants chat it up with each other.
But I can't recall a situation where the flight attendant has talked too much with me or at an inopportune time. If they are talking with passengers, to me that is them doing their job or even going above and beyond.
