Example #2: One time a gardener drove up in his utility cart and said "can't do that here". My buddy and I engaged him in friendly talk though. Eg.: "Really ? Since when ? We've detected this park for years". The gardener explained that his boss had put the word out to the workers to usher out md'rs. Because someone was supposedly leaving holes at another park.
When we heard the word "holes", we gave him a friendly challenge to look around at where we were all standing. Saying "We just dug a dozen old coins from this area. You can't see a single mark or spot, right ?" The gardener looked around, and agreed that we were not doing any harm. However, he was duty-bound to pass on what his boss had said. We persisted in friendly chat, and then he said : "When I get off work, what I don't see won't bother me". My friend didn't miss a beat and asked: "When do you get off work ?" He said "5pm". We looked at our watches. It was 4:50pm.
We thanked him and he drove off. My friend and I sat on a park bench till 5pm. Sure enough, at 5pm we could see him in the distance put all his tools away in the park shed, get into his city truck, and drove away. Whereupon we resumed md'ing. That was 15 yrs. ago. And to this day, I still hit that park now and then, and have never had any issues.
So there's a couple of examples of how not every single "scram" constitutes gospel law. Sometimes it means: Avoid that singular lookie lou, choose better times, etc....
