hi squeak,i would have thought that shop owners who love music would be players,also demos could be limited to lunch hours when the people are around and weekends when families are out shopping,i know if i passed a shop or forecourt and a good player was demoing a new,any keyboard i would stop as i am sure would many others,and if you was given a demo of how easy it was to play (even newbies who play one finger chords can sound good) sales would pick up,maybe you pro,s who work at gigs in evenings could get some extra work (if you want it) playing in these stores,mike
