shoo them out the door, point towards mecca and say GET!
Just did a search for myself to see which direction Mecca was and was surprised that both Facebook and Google wanted me to sign in ... other sights had headers that said Cookies were there to enhance my experience etc etc
Had no idea what a big deal it is ... but really since we live on a Globe I could pretty much pont any direction and the assholes would end up where I wanted them to go and that is away from me and towards their cube.
Really both Facebook and Google wanted my email address before continuing on with the search results.
Try it yourself ... “how to locate mecca”
