You do get some elders who let the position get to their heads. The congregation where I went, they woud not have allowed a brother to do anything if he had a noticeable beard. Even if it was just "I forgot to shave," some other brother would have handled microphones or read the magazine for the study or given a prayer, etc.
I cringe at some of these stories, and I recall hearing similar ones when I was in. We had a few snobby elders in our congregation, but they toed the line when it came to taking their job seriously. The snobby guys were mostly a problem behind the scenes, which made their progress even slower, which just made them more of a pain in the neck.
