Years ago I worked for an auditing company, and we frequently audited pharmacies. For many parts of the pharmacy, every single pill on the shelf was counted, one by one. Then a second person recounted just to make sure. A few unaccounted for missing pills could mean the manger of the store got fired, and probably legal trouble for the pharmacists. Missing drugs would be noticed, and investigated.
Some stacks of easily printed blank forms intended only as reminder cards for customers? Not so much. So no risk of the management discovering blank reminder cards gone missing.
