I went to ship a package and had to get my label printed by showing a UPS barcode. The manager first directed me to the self-service computer, which I had to pay to use, but then he realized that all he had to do was to scan the barcode I had in my phone. This mistake is understandable but he said he wasn't able to give me a refund. UPS employees, like everybody else, make mistakes, so the company should allow for refunds. At least the manager said I could get free printing next time I need to print something. Hopefully he keeps his word.
