From the original article in the thread:

> Those “rich fucks” kept Johnny on the road, mind, as he offered a racket-stringing service to players. Johnny has claimed he’s the only player ever to make a consistent living on the Futures tour, and he kept overheads low, running the school bus on vegetable oil. More recently, he has been making YouTube videos about “extreme couponing”, where he lists the great savings he has made on his weekly grocery shop.

Is it true that "You're not worthy to restring my racket" is a popular insult in tennis circles?

Nope, this isn’t Downton Abbey. The further you go in competitive tennis, the tighter the community gets. Also, playing tennis and stringing rackets are two distinct skillsets. For elite players the strings are just as crucial as the racket itself. Check out this interview with the stringer who traveled the globe with Federer for 15 years, ensuring he had nine freshly strung rackets for each match.

My HS coach was an Olympic medalist.
