No T, no credibility?

[lmeadski]

What do you all think are the consequences for NOT giving a T when a coach crosses the line? I coached for a number of years before reffing (this is my 3rd year doing varsity, 5th overall). I have been slow to give Ts, giving the coaches much rope. Do you feel the coaches lose respect for refs that don't whack them when appropriate? Or, do they appreciate a ref that is willing to listen and be patient with them when they blow a gasket? I used to think it was the latter, now I am beginning to question that.
