Atlantic Superstore review: Pharmacy

I shop at Atlantic Superstore 2 to 3 times a week and spend a lot of money there. Today I asked for Tylenol with Codeine, which I have asked for for years but today I was refused, because my other meds are at Shoppers Drug Mart. (Which is the same umbrella, in my estimation.) I find it convenient to get the Tylenol, while I shop for other things in the store. I am 74 years old, in great health and I would like to know "why" my request was refused. In this day of ready media, I do not feel it is in your best interest to deny my request. I have lots of friends and acquaintances and am well versed in media, having a son who works in broadcast media and although I know losing "my" business may not be important, I think you may lose much more than that by the time I inform all of my Facebook, twitter and Instagram friends of this pettiness. Is this a general rule, if so, I suggest you need to review this. I would like to know more about your policy, before I proceed any further. Maybe this was "one" person, having a bad day? Thank you for reading this and letting me know, if I can, or cannot, purchase Tylenol at Atlantic Super Store, Summerside, PE
