I often find myself saying - either aloud or in my head - "What is WRONG with people?" Sometimes it's for more serious actions, but I also use it for the stupid little things people do.
Like leaving cigar and cigarette butts all over the golf course. I mean, come on! Presumably, you'll repair your divots and ball marks in an effort to clean up after yourself and keep the course nice. So what's the difference? Do you have to be told to pick up your trash as well? Well, if you haven't yet, here goes...
I hereby dub it official golf etiquette (because I have that power) to keep all golf courses free of your own litter, including butts!
