I left my first band (in my teenage days) because the drummer kept throwing his drumsticks at the back of my head, eventually catching me in the eye as I turned around to talk to him.
I promptly threw my bass at him and packed up and left. It was a late 90’s unbranded P Bass and had apparently had a previous life as a boat anchor. Once he picked himself up off the floor (no real damage done) he quit, and so did I.
Strangely we managed to “fill in” as a rhythm section for another six months until the band split up because they couldn’t find our replacements 😂
No more drumsticks were launched at my head after that though!
