Here are my latest two pictures of my napkin art set-up...

     This is at Muddy Waters in the morning.

    
     This is at the bar at night.


     I can count on one hand the number of times I've sold at the cafe.  The bar is another story, though.  I sell nightly there.
     Lesson learned:  Drunk people buy more art than coffee-drinkers.  Why do you think they serve wine at art openings, duh?  It is to loosen up their wallets a little.
