I have a cousin who during his lifetime has owned a few McD's ... his first was on lower Broadway in the Financial District of NYC ... he brought in a Baby Grand piano and hired a guy to play from about 6:30 AM until 3 PM ...

I have played in a florist/greenhouse during the Christmas Holidays and have played for several Stop & Shop Supermarket Grand Openings ...

Like Donny says, 'do what you have to do' ...
