"I can't sleep."

The Doctor raised his head off his coat, not able to believe his ears. "What?"

"I said I can't sleep, Doctor—What are you doing down there?"

The Doctor shifted uncomfortably. "In case you didn't notice, there's only one bed. And how can you not be able to sleep? I had to wake you up about four times before we got here."

"In case you didn't notice, it's a double bed, and I left a space for you. And I haven't eaten in three days, I can't sleep properly when I'm hungry."

The Doctor sat up, rubbing his eyes. Humans. So hard to please. Rose was lying on the far side of the mattress, her exhausted face peering at him in the perfect picture of innocence. His annoyance quickly drained away when his own stomach growled. "Fine, food it is."

By now it was late, and the Doctor was too tired to try and figure out what exactly the time was in Earth hours but there weren't many people around outside. He and Rose wandered the streets for a while, trying to find anywhere open, before coming across a small, brightly-lit fast-food place with an 'Open' sign.

"We should probably go easy on the money," the Doctor murmured as they ventured inside. "We don't know when we'll be able to get some more. Fancy splitting a poubun?"

"What's that?"

"Local speciality. It's ... bit like a burger, I suppose, but a different shape and a bit spicy. They're quite big."

"Yeah, okay."

"Want a drink, too?"

"Yeah, don't mind."

The Doctor stepped up to the counter. "Could we have a poubun and chips, with a zonberry milkshake please?"

"Eighteen staples, sir."

Rose grinned. "Really? They have chips?"

"Rose, what kind of a friend would I be if I made you live on a planet that didn't have chips?"

"A bad one," Rose said dead seriously. "So what's a zonberry?"

"Closest thing on this planet to a strawberry," the Doctor replied, taking the tray.

"You didn't get yourself a drink."

"I'm not fussed, I'll just have a sip of yours if that's all right."

"I suppose so," Rose pretended to say grudgingly. "It was your yoyo after all."
