How does one sign OUT from a public computer?

Recently I signed IN to my eBay account on a PUBLIC computer, and neglected to un-check the little

box asking if I wanted eBay to keep me signed in. BIG mistake. Every time I come back to this public

terminal and eBay, it says 'Hi, Mark' in the upper left before I've signed in!  HOW DO I GET RID OF THIS?

It says you can remove this in one's My eBay, but for the life of me, I can't find it.  What am I missing?

My library makes users sign in to the public computers before using them.  When the user signs out, all cookies, browser files and other user storage files are deleted.  Then the computer restarts fresh, without any of the former user's information on it.

If your library is not doing this, you should be asking why.
