Unanswered Questions from Trader Joe's

Was some sort of diplomat at the grocery store at the same time that I was?

Do other medical specialties wear varsity jackets to Trader Joe’s that have the hospital’s seal embroidered on the back with “Department of [Specialty Name]” in script lettering over it and the physician’s name and initialized credentials embroidered on the front? Or is it only surgeons who do this? (This is not the first time that I have seen a physician a UCSD Department of Surgery varsity jacket at Trader Joe’s.)

Are the “big data” experts at Trader Joe’s corporate offices laughing at me because I am currently surviving on a diet made up almost exclusively of avocado toast and microwavable frozen dumplings?
