Itching to check your work e-mail or instant messages while sifting through carrots and potatoes? Now a trip to the supermarket doesn't mean downtime: the Morton Williams market, on 9th Avenue and 59th Street, has a big sign in the window announcing that free wi-fi is available.

In a supermarket? I can understand why free wi-fi is perfect for coffee shops, cafes, hotels and airports. But while food shopping, only the compulsive will need to stay connected, I would think. But bringing wi-fi to odd places isn't new. Last fall, XL advertised free wi-fi at the trendy bar and lounge. Just in case a look at Outlook can't wait for the end of that martini.
