Pharmacists and pharmacy techs are given "training" on how to identify supposed fraudulent sales. e.g. if your hair is long or you otherwise look like a person who would manufacturer amphetamines (whatever that looks like) they won't sell it to you.
So, congrats to you for looking like a fine upstanding person and not like a clandestine drugs manufacturer.
