A few weeks ago whilst in south Anchorage Sams' Club location, in the front area where food court & exit are located, was a commotion; some woman appeared to have fallen on the floor.

As I walked toward the front of the store, she had started gagging, coughing, & convulsing. There were about 4 to 6 people around her, so it was hard to tell if anyone was trying to perform CPR or some other emergency assistance. 

By the time I approached nearer, several employees were close enough to see the woman needed help. None of the employees appeared able, or interested helping. About then, I got to the front of the store (not far from the exit) a man was able to help the woman get an obstruction from her throat by performing some (abdominal thrusts) vaguely like the Heimlich Maneuver.

So apparently that business does not train employees in this kind of matter.
I'd think Sam's Club should've thanked him at least... Cheaper than a law suit.
