Weekend Warrior:

A musician who has a separate day job, which, to them, justifies their performing for low or no wages. Weekend Warriors understand neither the difference between a service and a hobby  nor what makes an amateur versus a professional, nor displacement, nor that we’re all in the same bathtub.   Those who consider themselves amateurs should perform at non-commercial venues (house concerts, busking) if they wish to avoid devaluing all other musicians in that market.
