The Uplink World

You enter the nearest shop.
By chance, it happens to be one of those all night cafés, offering low priced internet access and cheap coffee.
You can smell the cigarette smoke in the air, you can sense the hostility of some of the patrons.
A man in a grubby shirt and trousers approaches you.
"Oi! Yeah, you. Are you planning on just standing there, or are you actually going to buy something? We're aren't a shelter!"
What do you do?
