A strong opinion is still only an opinion.
I would say, "This is why we can't have nice things," but see, that isn't true. This is why I'm the only authority when I DM. To me this crystallizes why D&D has historically made the DM's word the word of god -- because if a group of my players were ignoring my polite hints, disrespecting me and my time, that's what not-so-random encounters are for.I've seen it. Not for hours on end... but I don't think it takes hours for it to be disruptive or counterproductive (assuming that not everyone is happy with such play, because if they are, then they can carry on).
I've had plenty of players who want to RP every small interaction. I've played in games where GMs roleplay out long scenes or speeches by NPCs. I've watched GM's carry out conversations between multiple NPCs where the players are mostly just watching.
In each case, it doesn't take that long for my patience to reach its limit. I don't mind people indulging a bit here and there, but I'm personally not there to watch the RPG equivalent of cosplay. If there aren't stakes involved in some way, if the interaction or scene isn't establishing something meaningful, then I expect it to be brief. I'm not a total jerk about it... but I will eventually speak up, especially if I'm the GM.
If they won't play nicely, neither will I.
