Bruh, I feel that this is especially true for US. In Romania, I could go to nearby stores or just leave or enter the school perimeter without problems during breaks. In USA, I went with a friend to his car during lunch break, because he had his sandwich in his car. When we came back we were searched for drugs and put on detention .We explained everything to the guards and he had his sandwich in his hand. A somewhat interesting experience but what the fook.
