Testing the food
When the President decides to eat outside of the White House, where the secret service and other people can check to make sure the food is safe, things can get complicated. They need to have a taster on site to try the food out before the leader starts the glorious feast himself.
Former leader Barack Obama had to stare at a plate of food all the way back in 2013 when a taster was not present with him to try it first. We bet that he thought it was a little ridiculous and that a simple cheeseburger and fries were not going to end his life.
