They pose as paramedics and quickly load your body into their state of the art Armored Personal Carrier, which is cleverly disguised as a simple ambulance. Once on board you're freshly dead body is loaded into a special experimental personal container that freezes time within it. Your locked in a stasis state until a time in which technology can advance to the point in which your specific condition can be treated. They already posses the ability to bring resurrect your body. However, it is some 40 years before the technology to remove the piece of cereal from your throat is developed.
Then and only then are you brought out of stasis, the obstructing piece of cereal is incinerated and you are revived in the medical bridge on the Flagship of the company's interstellar armada, currently stationed 39012.54 lightyears away from the Milkyway galaxy.
I on the other hand, am back on earth sitting in a lawn chair, on my lawn, just as the Earth's sun explodes.
