I have climbed the DC guided as well as unguided. Even when climbing guided I found that the guides were a bunch of abrasive assholes. Then again I find most people who try to spend every possible moment outside of society in the mountains to be like that, my own friends and self included. Let's at least be honest with ourselves that there is a certain no bullshit attitude you cultivate when taking risks on a regular basis.
I was roped to Jake during the climb he mentioned above. I was in the rear of our rope team and I was the one who talked to the guide. We were descending from the crater rim when the female guide started immediately talking trash about how much rope we had out between us. I did not say a single thing to her before this started. She just started complaining how we didn't know what we were doing and it was obvious because of how much rope we had out. We had about 40 feet I would guess which is longer than most parties. For us it is faster to descend with a bit of slack and a longer rope than short roping the entire mountain like the guides do. I tried to ask her for advice and offered that I am still relatively new and I am always open for advice, especially from a professional mountain guide! She was unwilling to work constructively with me and she demanded to be let by. I would offer to let her by and she would say something obtuse like "you guys are just going soooo slow." It was very awkward to offer to let her pass and to have her just talk trash instead of accepting.
We let them by when after declining our offers to pass she demanded to be let through. I felt really cheated how she had insisted that I was going slow, had no idea what I was doing, and should move out of the way for a faster party. As it turns out even in the flat open areas our team was able to move MUCH faster.
I can only imagine it gets worse when dealing with belay and rap stations.
