Re: best way to drop a band memeber?
Well, be honest. Beating around the bush won`t make any good results, on both sides, for both parties.
You should probably give him a hint by telling him that you have to meet to talk.
Although being "professional" regarding this, don`t be surprising and never ever treat it/him like a minor matter in this situation.
This "coffee-spitting" situation doesn`t make it sound as a very considered decision.
Honesty and professionality is so important. Being kind by explaining the problems in a constructive way is essential to keep a peaceful relationship in my opinion.
