All of them can be condescending and/or downright abusive depending on a lot of factors. I’ve found out if you have money they treat you better.
The very first time they visit your congregation determines how they will treat you for the next 3 years.
Their opinion of you will be formed based on the opinion of the elders and their wives, usually the host family.
Some notable asshole circuit overseers(Canada)
Terry Attick. Snivelling small man with a napoleon complex. Just a manipulator plain and simple. Gets angry when he can’t have his way.
Larry Erickson. I never had much trouble with him but he was very abusive to my Father and other brothers in the hall. He is a coward that uses triangulation and flying monkeys to do his dirty work for him. He doesn’t like brothers who work shift work. He is well connected at the Canada Branch through his wife’s family. He has the reputation of removing more elders than he approved for appointments.
