Yes, the BS can be thick. I have seen it on both sides of the counter. Sometimes it's misinformed people behind the counter, others they make it up as they go. When I was working behind the counter I over heard a co worker say some stuff that was complete BS. I waited until the customers left and tried to correct him, I was told I didn't know anything. I have also had the Delta/Seal/Ninja/CIA/Blackwater/ Space Shuttle door gunners of the 315th Mess Kit repair Div come up with some of the bizarre crap I have ever heard! The sad thing is, normal folks who just want to find out facts may get really bad info from both.
I know one time I had someone from the OHTF save my bacon, I had a customer ask me questions about class III stuff and I was over my head. He looked at me and asked if he could help answer the question. He gave the customer the info he needed, I double checked it later and was spot on. That was before I got my first SBR, now I am an addict.....
