When the president goes out to eat, who pays for the food?

When the former President Barack Obama visited Hanoi in 2015, he had the Secret Service scout a few local restaurants and finally chose a noodle shop (Bún Chả) to eat with the famous chef Anthony Bourdain. Normally this meal would be charged to the president himself, but since this is a scene for Anthony Bourdain’s TV series, he had the privilege of paying for both of them that night. Two portions of Bún Chả. Two Hanoi Beer. $6 in total.
