Small chuckle at the "play by the signs" folks.
Obviously when that's possible it's the correct thing to do. But that's not always the case. Unfortunately, not all courses have signage. Around here several
can't have signage. So it comes off as smug-but-ignorant when someone thinks "play by the signs" is a sufficient answer to this topic.
I'm so smug and ignorant, I make my own signs as I go.
We do a fair amount of verbal decisions/confirmations regarding OB, especially when playing new or temp or weather-impacted layouts. Always best to get this out of the way before a disc is in the air.

Surrounded by water ALWAYS out of bounds, even in the most casual of rounds. (Unless it's a shallow puddle that will dry up in 2 days.)
So a 2.5 day puddle is OB? Who monitors the puddle to determine final evaporation time (FET)?
For narrow creeks, I like in-or-across OB, because it leads to more fair punishment. Don't like to see people benefitting from a throw that's so bad it's beyond OB.
Usually a throw that's so bad it's beyond OB makes for a much harder shot than bringing the disc back in bounds and taking a stroke. Usually. Your opponent(s) should be allowed to make this call. Throw from where it lands or bring it back in and take the stroke.
I like to play sidewalks almost always OB, unless the fairway deliberately crosses over the top of the sidewalk. Aside from having a very clear boundary to add a new challenge to the hole, it also incentivizes safe play away from a public thoroughfare. Wrong side of walkway should also be OB. Similar logic to above, regarding fair punishment.
More importantly:
Everyone always plays 2 meter rule, right??

Most players in the USA don't know what a meter is.
