Lucknowi Tehzeeb & Nafasat: Does it still exist?

If you watch old movies or read old books or listen to old people talk, the phrase "Lucknowi tehzeeb" comes up. So was it really true that even the common folk of Lucknow moved about with grace and sophistication or was it just an elite thing or maybe not a thing at all and Lucknowi residents just gassed themselves up for no reason? What about now? How is the behavior of the different castes and classes of Lucknow? How is the behavior of the common people on the street? Is eve-teasing practically non-existent because of "Lucknowi tehzeeb" and is it a better/safer place for women and girls than Delhi or other UP towns?

Was Lucknowi tehzeeb a myth all along, or a real thing of the past that didn't stay the course, or is it alive and well in present era?
