I don't care about ID's either, but many if not most or all chemist staff ask the "100 questions" every time prior to supplying pseudoephedrine as if they are doctors and we are buying 24 pills at a high price (probably designed to control use through economics) for a meth lab. In these days it would not be beyond belief that happens, but.
We always use the same chemist, and because of chronic allergies and sinus problems in the family that even surgery did not help, pseudoephedrine works and everything else does not, so we are pseudo-regulars for a box every few months, and known to the staff. Still we are subjected to the questions every time. More so if we try to buy more during allergy seasons. Akin to guilty until proven innocent.
Perhaps a "trusted buyer card" (not a prescription with its specific amounts and limited refills) should be introduced for controlled OTC medicines such as pseudoephedrine, issued by a medical practitioner, to at least streamline the process. Show your card and get your meds with less time from the chemist staff and less angst for the customer, so a win-win.
