I'm thinking of serving beer in the high school cafeteria
Why would you serve alcohol in a high school setting?
I think it would have meaningful fun. Every day when I eat with my classmates in the cafeteria, I think that they also should have beer and have a good time together. It's a bit boring to go to school.
You shouldn't serve alcohol in a high school. If someone catches you'll get in trouble. If those consuming the alcohol get caught, they may snitch on whoever provided the alcohol.
I know that this is against the school's rules too, but parties are best when there's alcohol.
I know school can be boring and you wish it was one big party, but serving alcohol to minors is against the law and you could go to jail for that.
