Glad you got your rifle. As far as the "D*ck-Head" comment...If your dealer can't say for sure the salesperson was referring to him, then I wouldn't sweat that too much. I've been caught in that situation before. When I was young I said something to a co-worker that was for their ears only and a third party heard it and assumed I was speaking about them. Live and learn.
I would gladly let someone call me that if it gets me expedited service with overnight shipping.
