...Don't forget to tip the guy at the piano... Well I would, if I wasn't also sitting at the piano! Haha!
One place where I played regularly, an older Italian waiter gent would put a then 'still current' $2.00 bill in the glass tip jar at the beginning of my 1st set, for a visual power of suggestion to help the tips get started.
4 hours later when I was done, of course he'd reach in and take his $2.00 back.
But what was funny, was how some of those who got there after I had started, would kind of give him a double take, thinking he was 'stealing from the cookie jar'.
