Coach or first name?

[Raymond]

I don't address any coaches or players by name during games. Coaches are "Coach", and players are numbers.

I called a T on an assistant last week who used to teach my oldest son in 8th grade. I reported the 'T' to the table as "technical foul on the assistant coach with the gold tie" even though I knew his last name.

I don't want the slightest inference by anyone that I may be too familiar or personal with any participant. That just how I prefer to handle things.
