Not really... you can use a program to sniff the Airwaves.. then try and connect to them and try and get an IP etc... then see if you can get internet access.. but with WiFi gear being more available these days at an affordable price... Most Businesses are locking down there WiFi connections

Check out wookies info on WarDriving gives you a good idea about how to do it
