I have noticed a decline in the community as of late... Conversations like yours hate to say is almost the norm in DF, I personally have lost all hope in groups, and dread going into duties. Way to many folks don't know/care about their rolls. They wanna rush things to get it done fast, a fail on SE's part for making 14 into a grind fiesta. But what can you do, vote kick (only if others not grouped with that person), get kicked (Considering you stop doing your job they can report you on top of being kicked), drop out (take the 30 minute penalty = sucks). You really don't have many options...

I personally recommend to not communicate, when you do you feed these brats fuel, if they hit a nerve or keep going drop out let them find a new member and waste even more time.
