Just because I am hooked up to the Internet doesn't mean anyone can just wander in without an appointment!
On the other hand: I do not want to give the impression that I have something to hide. That would only be bad publicity. So you can take a look around.
Just remember that I'm watching you! And I'll also check your pockets when you leave. It's not that I don't trust you but safety first!
Have fun, stay as long as you like.
