I 100% agree that egregiously loud or repeated F-bombs (or other vulgarity) deserve either a verbal warning or a yellow card, and if repeated further, then a red card. While I wasn't the TD at BCO this year, for tourneys that I TD in the future, I plan on taking a more strict approach on overly loud or repeated vulgarity. Derogatory/Hate language warrants an instant red card.
But a lot more leeway should be given to non-vulgar verbal outbursts. We're playing a competitive game that has a physical/visceral component. For simply loud non-vulgar outbursts, I'm thinking I'd wait to hear from two different people/groups about two separate incidents, and then give a private verbal warning to the player to tone it down. If they repeat again, then yellow. Then red.
Because other than playing at someone's home collection for fun, I can't think of many pinball experiences where it isn't a loud environment:
- at the arcade, growing up, I heard much worse from the crowd gathered around the Street Fighter and Mortal Kombat cabinets.
- in bowling alleys, plenty of outbursts and vulgarity from bowlers.
- in bars, much louder and more vulgar outbursts from people playing pool, darts, Foosball, golden tee, and shuffle board.
- in pretty much every sport I know, competitors vent their emotions and frustrations on a regular basis.
If someone wants a library-like environment of people's volume level or responses to competing, I guess I'd recommend wearing headphones, or switching to golf or a quiet board game environment? (shrug)
