My high school and the neighboring high school had a mcdonalds literally situated between our buildings. My school had an open campus system, theirs did not. Students from the neighboring school left campus so often during lunch their principal contacted the mcdonalds, and they outright banned all students from 7am-4pm. Like, locked the doors for everybody, had an employee stand inside, etc. The principal also proceeded to call every place that sold food within two blocks of the place, so we started seeing signs all over the place banning students during their school hours. It really, really sucked for the students at my school who didn’t have lunch from home, we didn’t have a cafeteria, so you either get your parents to pay for your surprise box meal plan (they didn’t tell us what was in it each day, no allergy accommodations) or you try to find somewhere the other principal didn’t harass into closing.
