I have the opposite story. Friend collapses in front of the house. I pick him up and rush him to the hospital, he is a geek and we had spent great amount of time going over his rare genetic condition that randomly causes internal bleedings from his organs. No ambulance available but no traffic also, we arrive soon at the hospital. Only to wait for 1hr or more because he didn't look bad, since internal bleeding doesn't look bad, and his arrival time (or cause) had not been registered on the system since we came by car.

After we were finally admitted in the actual room the doctor said his ematocrit was lower than a dead person’s, but fortunately he was saved that time.
