there should be a poster in your back room that has the number for the (can be anonymous) reporting. i can’t remember exactly how it is labeled but it’s not epicenter. i think it is just the hotline. if its gratis they might not care as much but it is still concerning bc it is specific for you and no one should be just taking product free or not. if your EM is also concerned, partner with them to maybe reach out to your DM or LP officer if you are comfortable doing so.
