Certainly there are exceptions. There must be one nice courthouse employee somewhere.
In reply to your comment, their job is no different than any number of retail jobs I have worked. I must be nice to each and every person that comes in no matter how tiresome. Especially the ones that are in a bad mood.
It should be no different for the courthouse employees. But of course it is, as your making excusese for them shows.
And one of the reasons it is different for them is because the courthouse employees know the judge will throw the the &%#$@%$#@'s in jail if they get out of line.
And since you mention it, it's a lot like retail, and there ARE nasty sales clerks that don't get fired. In our local market the retail stores are hurting for employees, and you could complain all day but they can't afford to fire a rude sales clerk. You can't extrapolate from that that ALL sales clerks are nasty because they know they can't be fired.
See also my later post that crossed with yours. This judge has never before thrown a venireman in jail for contempt in over ten years on the bench. Looks like your generalization doesn't apply here.
