After work I walked to Walgreens to return some bandaids that I bought after I realized I still had a full box at home. When I walked in I went straight to the register which at the time had no line. Shortly after I got to the register two other customers followed in line behind me. I told the older lady at the register that I had a return and she said that it would take awhile and asked if she could ring up the two customers behind me first. I happily said yes considering that they each only had one item. After she rang them up about 4 more people were behind me. The Cashier then looked at me and said "I'm sorry but there is now a long line and there are customers waiting. Can you just go to the photos to get this done?" In the past I have been treated differently with service because of being a teenager but did not expect this from Walgreens. If it had been an adult in my position she would not have put my needs or service to the side continuously. It was incredibly unprofessional saying that "the customers are waiting" when I am just as much as a customer as they are and I had already been waiting. I was originally first in line and gladly let 2 customers in front of me. By that time I just wanted to get out of there and went to the photo register. The lady there was done with my return in a matter of seconds! The manager there should really talk to their employees about treating everyone equally and not putting a customer's return or transaction to the side because of their age. It was just ridiculous.
