Well done, well done, Bob and Mary. You’ve infiltrated every corner of our daily consciousness. You have banner ads on the web. Print ads in the Post. Posters above every urinal in every bar. Billboards in every metro stop and bus stop. Then you took it one step farther: For the legions of people in the District who shun public restrooms, don’t read the paper (online or in print), and are chauffeured around, you were even smart enough to find ’em where you know they’ll look—on the disposable coffee cup hand protector.I don’t smoke, but you’ve made such a good effort here that I just may quit anyway. Thank you, Bob and Mary.
