I found that by calling early in the morning, when Serj. first gets there, he answers the phone,dnad is is quite pleasant to speak too.
Rest of the day, he is in oneof his two machine shoops. Can't talk on the phone and run machines. Good way to loose a finger, hand, arm!
Those who have never worked heavy machine tools, cannot understand the attention required. I allowed NO one in my shop,land no phone. A simple ring out of the blue can spell disaster!
