I went in to pick up a little korg device I bought online, not knowing I was in the wrong section of the store for electronic instrument pick ups. I saw a desk at the back with a big sign saying "PICK UPS" so naturally I went there. When it was my turn in line I told the person at the desk (who was already eyeing me with suspicion for some reason) "Hi, I'm here for a pick up" and she angrily responded "... You're looking to PICK UP?!" like I had said something really offensive and unheard of. After giving them more details and being met with skeptical silence and blank stares her coworker figured out that I actually had to go to their keyboards section a couple doors down. As I walked away I could hear the woman I spoke to laughing about me with her coworker. You work at a desk which says Pick Ups in big red letters right above your head. Are you really going to be that shocked and unprepared for someone to tell you they are there to pick up an order? Even if they are in the wrong section? Is it really that crazy of a situation for you? You must deal with many different customers every day, right? Am I the first person to utter words like "I'm here for a pick up" at the "Rentals & Pick Ups" desk? Is it not likely to you that I was there to pick up my musical instrument from the musical instrument store?
