It would depend upon the job offered. I am only responsible for myself.Wy, would you want to work with someone who walked off stage because he was jealous of another player ... whose ability was making the whole band look good?
One cannot always be in top form, both musically and emotionally. We are human. I am not defending the man's actions. But I am aware of what musicians are like. The story of 20th century bands is full of people behaving badly. Whether it is Dizzy Gilespie spitting on stage during a Cab Calloway show, or Mingus attacking someone with a knife in rehearsal, musicians tend not to be perfect people. Being on stage is also not something "regular" people face in their daily lives.
As a professional who relies on work to pay the rent, it is not always so easy to pick and choose. I can only relate to the scenario through my own history and experience. It was only one show. I must say I also find fault with the horn player who allowed this nonsense to get the better of him and quit a working job with the band. A guy walks off stage once and he quits??? It seems to me the testicular region requires a little more girth.
For my part I would prefer to see what positives I could salvage with an eye to future gigs and income.
