Calling coaches by name.

[moref]

I just got my Officials Quarterly magazine in yesterday,and it had a very interesting article in it entitled( Whats in a Name?) on page 4. I do call coaches by name if I know both of them well, but if you only know one of them I don't feel comfortable just calling the one I know by name. I want the other coach to feel comfortable with me on the floor when he is on the road. I guess what I am trying to say is if he hears me calling the coach I know by name all night he might think he is going to get the shaft. I think the article is coming from a baseball/softball umpire, but it still fits in this topic. Do most of you guys address the coach as coach or by his name? I personally like to communicate by name if possible. Thanks in advance.
