This may seem like a side diversion to the topic, but it ends up coming back close to some of the main dilemas for finding solutions in situations like these.
Yeah, its an article about a ball golf course. Article about slow play at Gold Mountain in Bremerton (city course). It is a really interesting read if you read between the lines and apply it to what you know about people. (mind you, it not what you know about yourself
, but what you know about "people")
The article includes all that has been done in an attempt to lessen effects of slow play (which can be, and is, an ettiquete issue). They lay out how marshalls have tried to help, and how that sometimes works and sometimes backfires. It shares how some groups welcome help by outsiders, and some fly off the handle when approached. It really lays out a "can't win" situation no matter how you try to "fix it".
Then... go through and read the crazy comments that FULLY substantiate the diversity of responses people have to those experiences. Then think... how would I try to fix it? or just come away shaking your head and shrugging shoulders.
Then think of the parallels to our sports etiquette issues.
