This is in an environment with multiple people at a long open desk with patients on the other side of the counter. Someone sat down to check something, or check someone in or out, I don't know the details. They hit the Bookmarks button, and right there on the list was a PornHub link to something about a teen and anal sex. This caused a bit of an uproar about inappropriate use of the computer systems, though it may have stayed behind closed doors.
It wouldn't surprise me a bit if the person whose account it was didn't even know that bookmarks exist in Chrome - it's not like Google makes it obvious these days. I suspect there were some awkward discussions at home that evening, or possibly on the phone with college-age children.
