We're a 4am store; there is one veteran flow tm who always handles cardboard when he's there, so we're usually covered til around noon or so. If he's not there, another flow tm will take care of it. Dayside everyone's responsible for putting their own cardboard in the baler. Backroom tm or sometimes the LOD will make bales. Backroom, our receiver, and LOD have keys; if its a busy day, the LOD will just leave a key in it and whoever fills up the baler will smash it. Only LODs open up the trash compactor. We only have cashiers who are minors currently, so no minors are ever in our backroom- unless you count the vendor who was dumb enough to bring his maybe six or seven year old kid along one day lol. Boy did leadership have a cow over that.
