I ran into that also, when last time I went to a wrecking yard. Guy was pretty cocky. When I first walked in I told him vehicles I was looking for and he said good luck we don't have any.
I told him well what about the ones up on the hill in the back. Needless to say he let me walk back there and I found everything I needed but when he gave me the quote I laughed at him and walked out taking another customer with me.
