B.Y.C.

I know this may sound like a stupid question, but what is B.Y.C. and why do most people seem to have a problem with it/them?

BYC = Barnyard Customs. They make a-arms and have had difficulty delivering their products to customers who paid six months ago or more. I know of one fabricator who may and/or has already lost customers because BYC cant/wont deliver.
