BFD. There are thousands and thousands of restaurants in Delaware.
As I have said, you have no clue about Delaware. There are a grand total of 1,700 restaurants licensed in the ENTIRE state of Delaware. And that includes hundreds of fast food places.
Hey, a "survey" of 550 Delaware residents is considered legitimate when it comes to a smoking ban in a state of almost 800,000 - the number from 15 out of 1700 should be just as legitimate.
Give me your information of how good the ban has been in Delaware. You claim it's been so great - so you obviously have information beyond the PR pieces from the local paper which is decidedly in favor of the ban.
