It is one thing to defend a client because it is your job. It is something else altogether when they get totally into it. Makes you wonder what's in their closet, ya know. This guy has a little too much enthusiasm for his work. His picture is in the dictionary right next to the word "@$$hole." Most everybody I know has had run ins with him.
My boss doesn't, imo, get "into" it....but, he works very hard and tries to find those loopholes, too.
