Most CO's are high on themselves and their "great role" that God Jehovah is using them in. This is refelected mostly in how they treat the elders when they are there, occasionally some will allow their true selves to be seen by the R&F.
They are usually simonized by the biggest ass kissers on the body (usually the coordinator and secretary) and only listen to these ones when asking about the congregation. These are also the same guys you see giving parts on the Circuit/Special and District assemblies , the COs believe every word that they say. If you are an elder and don't go out during his "god's gift to you" week of activity you are essentially ignored. Essentially they are regional managers of a cultish, book publishing corporation, sent into the "retail outlets" twice a year to check on the Store manager (COBOE or other ass kisser) and the assistant manager (secretary or other major ass kisser).
These CO's are also not the poor, faithful brothers we think they are. If they get assigned to the right circuit i.e. somewhere in the Tri-State area of NYC they will clean up. Especially in the more affluent suburbs. I estimate based on what my wife forces me to give these yaya's when they come by that on average he will get anywhere from $400-600 just from our elders. Add to that the Minsterial Servants (especially prospective elders) and other publishers and he most likely rakes in $1000 for a week of b/s with us. thats 1 congregation in a circut of 14 or so. They have a choice appartment paid for that they live in, free utilities, gas, insurance, dry cleaning....you get the idea. Now granted this probably isnt the case for every CO in the world or in the U.S. but they do rotate so I am sure eventually they all get assigned to these certain areas at some point.
bottom line...screw all of them!
