Do the celebration after the medal off the track. If she had pantomimed the celebration and not actually set off a fire extinguisher, I'd take her side. Post Pandemic kids are something else....Using a fire extinguisher when not needed is some serious stuff. You can injure someone else or yourself. You have compromised a safety device for immediate future use. It’s illegal in certain places for a reason. Also, you’ve just opened up the copycat aspect so they have to make an example out of you so no one else is stupid enough to do this again.
People don't need to breathe that stuff in.
