There is an elderly woman working there who has an absolutely terrible attitude. The person ahead of me appeared to be deaf or mute; he seemed to be having an issue with a package—specifically, it belonged to a different courier service—but returns for that service are actually accepted at this location. She repeatedly insisted to him that he couldn't return it there and had to go elsewhere, yet in the end, the return was successfully processed right there. I was praying that I wouldn't end up at her window for my own return, but that is exactly where the line led me. She told me that my return slip was illegible, couldn't be scanned, and therefore couldn't be processed. However, I didn't leave; instead, I asked the young man at the adjacent counter for help. He was more than happy to assist me; he simply entered my tracking number, and everything was resolved very quickly. Meanwhile, she kept shaking her head, sighing incessantly, and even muttering insults under her breath. If she is so unwilling to work, she should just go home and retire.
