licensed or not of course you'll get people that are below standard. its everywhere you look and customer service is a thing of the past, it doesnt exsist anymore. That said, it should be like other business's, you should need a business license. Like being a golf pro, so easy to get a pro card but, most of these guys are just average. When I was a member at a particular course here, I can guarantee you that myself and 30 other guys where better than most of the pros. I watched people sign up to take lessons from these guys and it was painful. That said, they got their card and this is their job now. Its all about background info and word of mouth, do yourself a favour
