Feb 28 2017. I was in the Delta lounge at JAX.
Couple comes in with mid-size dog. They proceed to sit down in the room next to the food counter.
One of them ( not the dog ...) goes to the buffet table and gets an assortment of food, brings it back to where they sit.
They proceed to feed the dog his/her dinner, using the food they brought from the buffet, putting the food in the front of the dog on the floor.
This went on until the dog was satisfied.
