Back in the day I was interning with a friend of mine. One terrible band was in the studio and goofing around but everyone was in pretty good spirits.
The singer had a buzz on and stumbled up to the console and as he did, he spilled his drink on the Audient ASP-8024.
"oh, my bad...aw, sorry, brah" but not nearly as sincere as you would have hoped. He was still kind of

and laughing.
That ended the session immediately, on the spot.
My friend asked the entire band to pack up and leave immediately. I'd never seen him talk to anyone that way.
I think the band wound up kicking his ass outside because when they came back in to apologize & pay for the session the singer looked a little 'dirty'.
