You know what I hate?
When someone asks you to put an attenuator in their amp, urgently in time for a gig on 24 Dec; you do so; you drop it around to their digs; they plug in and love it and are having a good time; such a good time that they do a twirl and smack me in the face with the headstock and 6 Sperzels, with letting of blood.
Price just went up, buddy...
