I just witnessed something similar the other day while eating out. I looked up to see the family that just left the restaurant we were eating at suddenly screech their brakes, the Dad flys outta the car & grabs his maybe 3-4 yr old and do the Heimlich right there in the parking lot!
He was successful in dislodging the free candy mint that his son had picked up on his way out of the restaurant. Poor baby was crying afterwards...cuz his candy fell on the ground!
