Someone from HR actually hung up on me, lmao!

They called me up about an item we received in procurement that they did not do a purchase order for, so I can't deliver it to them. They tried arguing, saying they need it today for something, but I explained that it's department policy not to deliver things that we don't have a purchase order for, so my hands are tied. They then said all quickly with an attitude "Well, that doesn't work for me," and slammed the phone on me. Lmfao, a higher-up over in human resources! Way to lead by example.
