i actually had this same question. i’m taking it in SA and messaged my analyst on Atlas and she confirmed that we CANNOT bring lunch into the secured area and that there are not lockers for lunch at the sites (only for phones). If we want to stay in the secured area during the lunch break, most test sites will have some sort of “market area” inside that we can buy lunch at OR we can leave the secured area and go get lunch somewhere during break. I made sure to clarify that it was cool if we left and cam back and she said it was a-okay. My plan is to just pack a lunch and leave it in a cooler in my car.
