Visited the location Niagara Store #858 - Montrose Road-Once a loyal customer- The pharmacist refused to sell my granddaughter Acetaminophen (I asked her to get for me while shopping) James the pharmacists tells her "no" ...yet when my daughter went she was able to buy it. I found this out and approached this rude member asking "why did you refuse to sell to my 23 year old granddaughter yet sold it to my daughter. With his pompous rude attitude said "Cause I can, I don't need to" He repeated this over and over. Then he bluntly lied. One thing to say "oh we are out of stock" he just simply said "No" no explanation. However when I asked him why he repeated " Cause I can" Rude. I spoke with the store manager letting him know of this situation...next thing you know a staff member that was behind the pharmacy counter came into the conversation and she too lied...stating "It's a narcotic" Yet when asking her now why they refused she as well lied and stated "oh I could see her mother was buying it" yet How on earth did they know my daughter and granddaughter were related they both stood at different windows far apart from each other;... she as well lied and told me to "watch it" this being a threat...Never had I ever dealt with such unprofessional behavior. When I know this "James" person is working I avoid him as often as I can he is horribly horribly rude...not what you would call a people person. Do a mystery shop on him so this could be validated. Rude and unprofessional liars. Competition is strong here...this store can be bypassed...He certainly is not a "people person" Horrible horrible Done!!!
