A friend of mine and I played on a team together, and then he quit after the last season as he was on like 3 other teams and couldn't fit them all in.
Anyways, for our first game of the season last week, we ended up having only 4 players. My friend played directly before us that night so he ended up joining us as a sub, and someone else from our roster showed up about midway through the 1st.
We go through 2 periods and we're winning by 3 goals, and then midway through the 3rd, one of the league's "managers" (there's not really a structured hierarchy; there's like 3-4 people who take turns running things and one main guy who organizes it all) comes over and she's REALLY mad, and she informs us that the main guy is mad as well. (both people are usually VERY level-headed, for a bit of context) Apparently my friend wasn't allowed to sub for some reason, even though he would have played for us if he had the time. My friend had to sit for the rest of the game, and I got the impression that we were "formally" reprimanded, though I didn't hear anything about any additional punishment last Monday when I came back for our second game.
What was also stupid is that I believe someone on the other team went and complained, even though they had an actual ringer from like 3 divisions above us.
