I will openly admit that not all WCOs are the same. It could very well be, that you aren't like that. But there are some really bad apples out there.
I will also admit that I have met a couple WCOs that were very friendly. Met one in western Greene Co. about 5 years ago. One heck of a nice guy. My father and I chatted with him for about 20 min. Unfortunately I don't recall his name. Very professional!
I have to say though, most of my experiences have not been good with the PGC. Seems like just about everyone has had a bad experience with at least one.
