How the hell do I sign out of GS on an iPad?

I'm using a friend's iPad to order my new PC parts, since my laptop is fried, and I signed into GS to ask a couple last minute questions on the PC forum, and now I can't sign out. I can't get the drop down menu in the corner to show up. It's like the iPad can't detect the click on the arrow, and just goes to my profile page, like I'm clicking on the avatar pic. I even deleted the stored information from GS, through the settings menu on the iPad, came back to check and I'm still signed in. Is there a page anywhere that just has a nice big log out button?

@the_bi99man: easy enough..is the browser set to private? if so,close the tab and clear the cookies and cache,go back to the site again to see if it's on a fresh start
