What's the worst adult tantrum you've ever witnessed?

I was working at McDonald’s at the time when this happened. Everything seemed to be going normally. I took this guy’s order, told him the total, and he handed me money to pay. I then gave him his change and receipt. Now he was not happy with the change he got back. He started raising his voice and going off about how it was my fault for not telling him that he didn’t give me enough money to get a full dollar back. I just stood there while he belittled me, yelled at me for not saying something and that I should have know he didn’t want coins back. I was like 15 at the time and this grown man decided it was my fault for not reading his mind. Other people were watching, so he eventually stormed off while I was trying to hold back tears.
