There were a few... My brother and I were singled-out because we had an unbelieving father and we were really poor as well.
For instance, one time, my brother's pen blew up during the meeting and he ended up with ink all over his hands. He went to the bathroom to wash it off and, not thinking, he pushed open the bathroom door and got ink on it. He was not baptized at the time, was still in his early teens actually. He got dragged into the back room with 3 elders who determined that he could no longer give talks or comment because he "defaced Jehovah's house". Instead of just handing him a bottle of Windex and a roll of paper towels, they decided to be a bunch of pompous fucktards about it. And it took FOREVER for his privileges to be reinstated...I wanna say over a year.
When we were really young, still in single-digit ages, there was one elder in particular who really tried to make us miserable. His wife was a sweetheart, but he was a POS. Always yelling at me and my brother for something or another...stupid stuff like talking too loudly after the meeting (when other kids were YELLING), walking too fast in the hall (when other kids were RUNNING), and sitting on the steps of the stage. I grew up thinking the stage was "holy ground" or something because it was such a BIG FRICKIN DEAL if you dared to SIT on it. I remember many occasions where this asshat grabbed my brother by the ear and DRAGGED him over to my mother over something petty and ridiculous. And on top of it, my brother would then get his ass beat when he got home because he caused my mother to get counselled (when really, it was the elder making a big deal out of nothing).
I've dealt with my fair share of pompous elders as well. Window washers and carpet cleaners by day; judge, jury, and executioners by night. Example: My mom was overlooked in the congregation a lot when I was a kid. I mean, she practically jumped out of her seat with her hand raised yelling "Ooh! Ooh! Pick me, I know it!!" and whoever was on the platform at the time (usually one in particular) would look right past her, or look right AT her and then call on someone else. Never failed. There were times when she would go 3 or 4 meetings without getting in a single comment, even though she raised her hand for every question. She was also overlooked for talks. I mean, she went a year and a half one time without giving a single talk, and yet it was always the same sisters in the rotation giving talks 2 or 3 times in a 3-month span! And forget about demonstrations! So finally she asked to meet with the elders so they could figure out what the problem was and how she could contribute more to the meetings. They sat back and accused my mother of wanting to TEACH THE CONGREGATION LIKE A MAN! That's not what she was saying at all! She just wanted to comment more and be assigned talks like every other sister. And yet, they made her feel like absolute crap for even deigning to think she could be like everyone else. My dad was present for that meeting...he refused to let her go in and deal with those assholes alone... He wasn't a JW at the time. My mom walked out of there crying, and my dad stayed behind and told the PO "Listen you little fuck, my wife has to be nice because she's a baptized Witness...I'm not...and if you ever make her cry again, so help me God, I'll pound your ass into the crack of the fuckin' sidewalk...are we clear??".... Interestingly, mom got more talks and got called on more after that lol.
ETA: When my brother approached the elders for reinstatement, he had been going to a different congregation. The elders in his congregation asked the elders in the old congregation for my brother's records. It had been over 6 months of him attending meetings and working his way back. The elders in the old congregation refused to give up his records! These were the same elders with the ink incident as well as making my mom cry. They tried to dig in their heels and say he HAD to go to that congregation and they tried to make him start from scratch again and attend for 6 MORE months. But the elders in the new cong fought and eventually won. Right after they got his records, he was immediately reinstated. Not only that, but his DF'ing was very shady to begin with... He had been seen smoking and said he was going to quit. Then they brought up his worldly gf and asked if they'd had sex. He said yes, and that he was sorry that it happened before they were married. They asked "Will you have sexual relations with this girl again?" He said..."Well, we're getting married, so eventually I will be, ya know?". And they DF'ed him.
