Me!
I have a very good friend off the course, but when I play golf with him I shoot way over 90s or even 100s. This guy constantly talks and talks, uses his mobile phones, during swings, during puttings. And the talking is so constant that when he actually shuts up I can still hear him ringing in my head.
He does not have any golf etiquette whatsoever, or does not want to understand rules! constant muligans, swinging and cleaning the flowers in the flower beds, bunkers and if I impose penalties he says that I am a snob and calling me "a failed golf pro wannabe" and "too much rules!"
What to do????
