NWA, don't take it personal. Sometimes "Have a great weekend" can set off this group.
As for the first comment resulting in a barrage from the official, you may have been the 20th person that day that asked him to watch for a particular act. Thus, you took the brunt of everyone's transgressions. It is similar to a coach of a team that has to play a back-to-back and one of the officials in game one acted like a jerk. The first call he doesn't like in game two may result in a Bobby Knight tantrum. The official will wonder what happened just like you are wondering - course you will be gone while he's wondering
As for touching the line, I have not worked with anyone who would not whack you for that. Personally, you can complain (or whine) a little, but show me up and I'm probably going to get the last word...especially in summer ball.
Just my thoughts.
