Why do people who are supposed to be professionals do this? Is it poor training? Apathy? A flaming case of "Not My Problem - Pass It On"? As a first responder, my level of training is somewhere between basic first aid and EMT, but I certainly know better than to mistake a twitching muscle for a pulse. And if they were concerned enough to call an ambulance, why then did they not bother to alert the front desk?! I would have been furious myself, and think you handled the situation well. I do wish, though, that there were some way you could make some formal complaint. Abuse of the ambulance system is dangerous!
