I went to return kegs from my wedding. The guy that was working was still getting dressed so wouldn't help us. Then then the girl that did help us was extremely rude. We didn't know to bring in our original receipt so she was clearly very annoyed by this although it didn't seem to take long to take care of it without it. She then proceeded to make sure to let us know "for future reference bring the original receipt". I was kind of shocked how rude she was.
The cashier and the manager that she needed to finish out return were super nice.
