I had my Chromebook with me this morning when I made a trip to a town 20 miles away.
I stopped at a McDonald's, because my grandson was with me and he wanted to go there.

I couldn't get connected to their Wi-Fi.
It wouldn't give me the agreement page.
Although the Taco Bell across the street did.
And I saved this from them.
