Each night (and brunch) we put out our sandwich board. I've been chronicling some of my favorites.
Once we wrote that Yo-Yo Ma was playing and several people came in to ask if it was true. One night, the statement, "a doughnut without a hole is a danish" brought a woman in asking if she could buy some doughnuts.
We have no uniforms and several of our staff members have plenty of colorful t-shirts in their wardrobes.
Cheers!

As you go through life brother, whatever be your goal, keep your eye on the donut, not on the hole.
