I spent 20 years (the 70's and 80's) making my living as a full time bass player, and the last 30 years as a part time musician with a day job. I have always considered myself a professional, and I will only work with others with the level of professionalism I bring to the table. Call me a snob, but it's not fun for me to work with rank amateurs. Suit up, show up, do the job (i.e. perform), get paid.
