I used to teach beginners for fun, I have no credentials, but as an amateur, they had no cost
.
Mostly my wife's friends; I really enjoyed teaching, so much so a friend that ran a range in Norton, MA had to ask me to stop as his teaching pros were complaining about me. I told him these people would never pay a nickle never mind $50. I understood and had no issue with his position...
Back to the subject at hand. Every beginner I taught I told them to tee it up in fairway for a while for enjoyment . I fail to see how putting a peg in ground slows play?
Honestly a large portion of golfers I meet believe that a golf ball is struck on the upswing. They should use a tee themselves
