Unsecured Wireless Internet

If you are at a hotel, or similar public place, and your laptop detects an unsecured (no password needed) wireless signal, what do you do or would you do?

(a) Try and work out where it is coming from, and let them know it is unsecured so they can fix it

(b) Don’t use it at all, or notify anyone

(c) Ask the hotel if it is theirs, and if so use it, otherwise don’t use it

(d) Connect to it and use it for your normal browsing and e-mail

(e) Connect to it and start downloading 350 MB television shows so you don’t go over your normal data cap at home
