Scolding by marshalls, at least in the US, will be promptly answered by 1 star reviews on Google. "Your starter is incredibly rude" is the most common verbiage.
I think an off-topic discussion of marshalls/starters interaction strategy could be fascinating. I certainly know it's an impossible job to police your own customers, but I think it's a place where courses with the budgets could really benefit from highly skilled people to handle these situations.
I know one of my fondest memories of my visit to Pasatiempo was that the starter seemingly-genuine interested in the idea behind the wiki, and walked me through every hole, giving me incredible notes, and pointing out on the map I'd printed out where these features were. I'm very proud of the
course guide that came out of that 10 minute conversation, even if it's had a few edits from kind strangers in the last year-and-a-half.
The starter at Northwood had exactly the opposite reaction. When I started explaining the project, he moaned "just tell me what you're trying to sell already." I told him that I wasn't selling him anything, and the point was that the guides are free and could be helpful to players, handed him what I had, and just walked away.
I've have very similar reactions in groups suffering from pace issues. Getting barked at because "we're two holes behind" after a group ahead of us quits because of slow pace, while at other courses, having a marshal talk to me, realize I'm a thoughtful, 20+ year player, and basically working with me to encourage my foursome to pick up the pace. I've had friends yelled at... at beginners' par-3 courses, for not having perfect etiquette. It's wild how much these interactions affect or impress me.
If I ever end up working at a course, it'll be a focus of mine. I know that the starter and the marshal wield so much outsized power that when I see a course that has a thoughtful starter/marshal, I make a mental note, because I suspect that thoughtfulness will exist in other nuanced corners of the business.
