Peter Chang Arlington: Mystery

Today I saw several empty packages of commercially-made food items ( I presume from the same sized packages with same bright red wrappers); and on top was an empty package of “Crystal Shrimp Dumpling with pork added” (photo). I saw them in the small hallway trash can near the restrooms. Do you think these were purchased by employees to cook and eat for themselves? Don't restaurants usually feed their employees? (PS, there is no such dumpling on the regular menu).
