a-priori

How often have you gotten stabbed by the urchins' spines?

Really? I remember once my dad stepped on an urchin in St. Lucia. It got him in one of his toes, and the toe turned all blue and swollen.

I take it that's not how you spend every day? :)

That's cruel for the operator to laugh at you. Seizures are scary things... I remember the first time I saw my wife had one. Even though I knew how to handle it and I handle emergencies well, I'm not embarrassed to admit I was really scared. I was rattled for several hours after it happened, and for weeks I got freaked out anytime she got lost in thought.

For future reference: A seizure is not necessarily a medical emergency unless it lasts more than 5 minutes. But it can turn into one if the airways are blocked (e.g. by food), an injury happened in the hours leading up to the seizure (e.g. head trauma), or they injure themselves during the seizure (e.g. by them falling into/onto something). Finally, and this is really important: a seizure is an emergency if it lasts more than 5 minutes. In any of those cases, call 911 right away.

Otherwise, get them into the recovery position (most importantly: lie them flat and turn them onto their side) and clear the area of anything they could injure themselves on. Then watch the clock, monitor their breathing, and wait for it to subside.

But really, if you're unsure what to do then call 911. They'll either send an ambulance or at least talk you through handling it correctly. And if the operator laughs at you, tell them to fuck off and get you an ambulance.

Then complain to their boss.
