Can I yell at someone for farting in a bar constantly?
Why would you yell at them?
Because I had to listen to it for long time.
I see your point, but it's mean to yell at people. You should settle your differences peacefully.
When it's a matter of hygiene, I'm not afraid to say my opinion... I'm going loud, respect that.
What they are doing might be rude but yelling and disturbing people is even worse. You never know if they have a medical condition that causes this.
