Nearly denied for the purchase of a camshaft on my 'pre smog' California vehicle

I must've gotten lucky with summit in the past. I had a similar experience buying a cam kit once. The lady asked me if this item would be used on a street car and I answered yes.
She said, "okay, let me ask you again, wink wink."
Then I said no and she laughed and said, "Oh good! Now I can sell you your parts!"
I'm sure she was just following protocol. She had a good sense of humor about the whole thing.
