As a wrestler who cut a lot of weight, we always went to the locker room at lunch to chew instead of being tempted by food ( I realize how dumb this was now). No teacher that went into the locker room cared and looked the other way. None of us were of age but different times I guess. We were a rural school so that probably had a lot to do with it but I have no doubt that wouldn’t fly now. I was in school over a decade ago.
