And when you're finished using that public computer, be sure to clear your browser's cache and cookies before logging off.
This will help prevent the next person using the computer from knowing where you've been on the Internet. Some cookies are written so poorly that they store your passwords and other personal information right on the computer, so another user might be able to retrieve that information.
This is also a good habit to get into, even when working from home or the office on your own laptop or PC. If Internet Explorer is your browser, do this by selecting "tools" -- "Internet options" and clicking "delete cookies," "delete files" and "clear history."
