Hello,
Yes, I had a reading at a local psychic fair about six months ago, and at the end the reader used Lenormand. He used a lot of cards (a few too many if you ask me), however, his messages were great. At the end of the reading he gave me a free crystal and also pulled a few cards from Lenormand. Great experience and the second deck kind of reconfirmed the regular tarot deck. Loved it!
I have a few readings in my shop where I combine regular tarot with other decks. I find that it gives you a bit more meat on the bone - you have the traditional tarot as the main meal, but you get added bonus messages from the second deck. Amazing how it works!
Not sure why Lenormand isn't used that much by professionals. Personally I prefer larger decks...that could be one reason?
Love and Light to you!
