I didn't realize we were only talking about tournaments. That's fine, I understand the need to finish in a reasonable amount of time.
I think the topic was wider than tournaments.
I answered your question evoking them, as they would be a context where time constraints would exist.
Now, even in a friendly game, when a player drags too much, it can be straining for their opponent.
I mean, when a player takes twice or thrice the time that their opponent, all things equal, it can be annoying.
Mind you, I do play with opponents who play much more slowly than me, so I don't think I am overly intolerant.
But when a player freezes five minutes before rolling their WDR or before routing a brokie along the only possible path...
However, as I play most of the time on VASL, I can go on forums answer rules questions, etc. while my opponent drags their feet.
I wonder if some very slow players are too burdened about the aim of playing the perfect game, and freeze even for quite inconsequential actions?
Pondering upon the fate of that 4 morale conscript half-squad stranded in open ground under enemy fire, too far away to reach a victory objective, is most often a waste of time.
OTOH, I am personally under pressure when it is my time to play: I hate to make my opponent wait too much.
But that is my inner "superego"/conscience tourmenting me, because my tendency is to be an "adapted child" from a transactional analysis perspective.
And it can be a flaw, if I (secretly) expect other people to have the same psychological profile.
