That's usually not the case, esoteric questions of the rules usually arise because parties have read the rules and at least one of them thinks they have found a clever exploit, and at least one disagrees.
> people go asking the lawyer
The parliamentarian, who may or may not be a lawyer (and when they are, very often so are a lot of the members, and anyhow, while there is a similarity to the roles, they aren't, at least relevant to the task at hand, being employed to practice law per se, except to the extent that the body is one whose rules have legal force.)
Most of the time people stick to some subset of the rules they have seen used before, but every now and then they get annoyed when someone else seems to be taking some liberty and they challenge it; at best this is because they have some vague memory of that being wrong, but more often it is because it feels like it should be wrong.
(My favorite example of this was one time I saw an eight hour long meeting get ground to a halt as the chair of a student government asked the supporting staff member to "do me (her) a solid" and search their old minutes to see what they did the last time they had this same argument, as they had all determined later that whatever they had done was wrong.)
On the "parliamentarian"... if you even have a "parliamentarian" (omg lol) you probably are in the category of group where Robert's Rules of Order might have even been designed. Most governments (not by area serves but by count; these are all the small districts and cities) are at most five elected or appointed board members, and they have access to a city/general manager and maybe (if they can afford the luxury), a lawyer. (My government decided we can afford access to a lawyer every other meeting. I have seen many governments that never have lawyers available during meetings.) The idea that any of the governments I am a part of would have access to a "parliamentarian" feels just absurd to me... :(.
("Source": I am an elected government official who was further elected by all of the local special districts to serve on the meta-government that creates, modifies, and destroys other governments; and I am further the kind of person who then--with glee--attended both the big annual conferences for my kind of government as well as of all of the meta-governments to talk about all of the different kinds of government ;P. I work with a lot of governments, and I'm seeing everyone migrating to Rosenberg's Rules of Order.)
In a well-run meeting, this sort of dispute should be dealt with by the chair simply taking a decision— The chair’s rule is final, unless overturned by an immediate vote of appeal.
Everything else is about making things go smoothly by setting everyone’s expectations about what the chair’s rulings will be.
Exactly this.
And to add on: if the members (in aggregate) do not trust the chair, then it really doesn't matter what rules you use (or don't use)—you're going to have a bad time.
For small or less formal organizations, trust in the chair may be all that you need. For others, condensing those expectations into a set of written rules helps maintain organizational transparency and coherency.
Here's a funny clip of Barney Frank filtering them. You can tell all the participants are fully aware of the effort to game the system:
> (so large that you would rather do anything than separately ask everyone for their opinion or even their vote on a matter... the "voice vote" mechanisms are thereby designed to try to shortcut real votes)
My brief time as a parliamentarian for college meetings suggested the opposite is true: voice votes (yea/nay) on the question are a great shortcut for small meetings when you can trust volume is count rather than emotion (and only need to ask "all those in favor? [aye]" and "all those opposed? [nay]"), but gets unwieldy fast in larger meetings where you either have to the ask the question individually to each member in a voice count one at a time or switch to a hand or ballot count.
RRO, from my reading, was built to cover the gamut of small meetings and large meetings, it wasn't focused on one or the other, and most procedures (especially in later versions) are as much about splitting large meetings into smaller sub-meetings as anything else because smaller meetings will always be easier to manage and faster to run.
Some people have come up with variations as well:
“The [Grateful] Dead still meet about once a month in a boardroom to discuss their projects. Initially, the meetings were free-for-alls, Garcia says, but somebody dug up a copy of ‘Robert’s Rules of Order,’ and they riffed on it until they had devised their own warped version of parliamentary procedure.”
Bill Barich, “Still Truckin’,” The New Yorker, October 4, 1993, p. 98.
Not so sure these are actually very useful a quick read finds this gem
"There can be up to three motions on the floor at the same time"

I thereby will suggest people take a look at Rosenberg's Rules of Order--which its author, Judge Dave Rosenberg, subtitles "Simple Rules of Parliamentary Procedure for the 21st Century"--which is what many smaller governments in California have been standardizing on using (and so if nothing else, maybe you now need to know both, as these are actively being used ;P).
