In league it is important to call the rules fairly. People are there to learn the game and play it correctly, even when starting out. If it were a friendly game (i.e. no money on the line, not a league, not a tournament) I might do something different. If a total beginner I would tell them in a friendly way that we could spot the balls and they shoot again, but next time it's BIH. If anyone over a total beginner, we'd probably have a chuckle and I'd take BIH.
Usually a total beginner is having problems even making a bridge and stroking the stick correctly. It can be an embarrassing thing for an adult to deal with. No use making it worse, we've all been there, just some of us got that phase out of the way when much younger. Add to it that many are just totally frazzled mentally after the last couple crazy years and you gotta show some compassion. No use causing them anxiety in a friendly game that they are just learning.
Once you see that they have found some beauty in the game you can more seriously discuss rules and strategy. Gotta crawl before you can walk.
I've done it myself. I've seen friends do it. The one that got me is the 9B. I lined up a shot and the CB and 9B near each other. The 9B was positioned in such a way that it was pretty much white only while lined up with the shot. Now normally I'll take a quick glance at the CB, but I was in dead ass stroke that night and didn't. Saw the shot, lined up, shot the OB perfectly in the center pocket. I hear a giggle... look down and I've shot the 9B instead of the CB.
When lining up with your peripheral, you can't really see color well (try it, have someone hold a red or blue pen in your peripheral and you'll see it but not the color). It happens.
Also on occasion we play for too long without a break. Sometimes we get tunnel vision and focus on the wrong ball. We've all shot a ball out of order. We will usually let each other know if we know that's what's going on, though we don't like to interrupt as it can be sharking.
"Hey boogie, 4 comes before 5." "Yeah I know, I was just lining up my next shot!"
