Usually, the places where I speak will have some sort of sign by the entrance, indicating their preferences/rules.
In most business settings, there will be some request that cell phones be turned off.
In others, there will be some dress requirements (sometimes having to do with uniforms.)
Yesterday, as I got ready to walk into Woodinville's Tot Spot Café, it took me a second to fully grasp their request:
"No Green Boogers Here."
