Three things that piss me off on a golf course. #1 is someone telling me they carry a 6, and it ends up being a 28. I've "ditched" groups for that and went back to the first tee. I know, a little petty. But, if I'm on the green in two, and you are hitting 6 and you're still not on the green...yeah, "I'm outta here." You could have told me in the first place and I'd wait; even help.
