I think it is a different situation when you already are familiar with their company (ie. friends for some years) and they procrastinate about leaving.
First of all, while for some may be a technique, for others is just natural to behave this way. At worst is a kind of manipulative deceit, and yet it is effective in achieving its goals, to stay with other people long enough that you may have more chances to hear something from which you could benefit. On the positive side, you get carried away by emotions, which is a thing NTs like.
And I don't think it's that a different situation. My flatmate did it as a routine, and we already know each other.
