players talking to ref's at the end of time outs

[slow whistle]

Similar to dealing with coaches you have to do whatever is comfortable to you...I was always taught that in an ideal world we like to have players "on our side", (so the next time you have a problem with #42 white, you have established a repoire with #50 white and can say "take care of your teammate") so there is nothing wrong with engaging in a brief friendly exchange with a player...you don't want to be a clown, but being friendly or cracking a joke with a player is perfectly acceptable if it is part of your routine/comfort zone...my two cents and what has worked for me..
