Hi @galenkp.
I think this has happened to many of us and the truth is that it gets quite annoying.

I remember, about 37 years ago I was at a party for a young lady who was turning 15.
She was the daughter of some friends and the parents had asked me to help organize the activity because I was also the teenager's teacher.
Everything was going well, until an uninvited school teacher arrived with a few too many alcoholic drinks.
He started messing with the guests, did things he thought were funny and had to be forcibly removed from the activity.
When he was taken out of the house he started to assault by throwing rocks and it didn't end well.

There are people who don't understand their place in an activity or need to be the center of attention and will do anything to achieve it.
There are others who do things like that under the influence of alcohol, although the person who drinks should be responsible with it.

Sorry for the length of the comment.

Happy day.

Cheers and best regards.
