Bad Customer Service

To whom it may concern,
Today around 1130am I went to Shoppers Drug Mart in the East end of Woodstock and had horrible customer service. I am expecting my first child soon and had a coupon for “Similac Mom” supplement. I could not find it, so I looked around the store for 10 minutes trying to find any sales associates. I finally gave up and went to the cashier to pay for the rest of the items. I decided to ask cashier if she knows if they sell them. She was unsure so she paged a merchandiser to the front desk. She put my order aside to ring through other people in line. After waiting 5 minutes she paged again for a sales associate because no one came up. The cashier quickly left the desk to browse down the aisle to see if she could find it. With no luck she went back and paged again because she thought they could be at the back of the store with the other supplements. Finally a worker comes up looking awfully angry and snapped at the cashier “You know when you page us you can ask for Kathy or myself!” Then the cashier said I was trying to find this product but can’t seem to find it anywhere. Then the associate snapped again “if you looked why would you page me! It is probably an American company so we don’t have it!” Then I spoke up and said actually if you read it is says “only applies to Canadian stores”. I felt extremely uncomfortable that I didn’t even care if they sold it or not. All of this was going on while the cashier was ringing customers in. The other customers in line were appalled with this woman’s behaviour. I feel extremely bad for the cashier to be verbally put down in front of customers; while she did everything she could to help me. I will most defiantly will never shop at Shoppers Drug Mart, east end Woodstock again.
