I've personally never had it officially. I was more apt to see girls on my own, and then they could me pengrah separately. The added pressure of a full fledged introduction would be annoying I think. So it usually didn't happen until it became something more than fleeting.
That said, the first meeting with sourgirl was all 4 of us. Its blossomed quite well that way.
I am not sure how I would take it as a requirement. I might think of it as a yellow flag.
