"You've got to be kidding." Bernard pointed to a sign above the bar. Please do not ask for credit as the subsequent decapitation often offends. "The only people I give credit to are time travellers who paid me back yesterday."
"But what if we invent a time machine in the future then come back and pay you yesterday?"
Bernard smiled. "Then I'd give you credit--"
Dill raised his hand.
"—but you didn't pay me yesterday because I'd remember."
"Oh." Dill sighed. It wasn't easy because he had to consciously fill his lungs with air and expel it again. "Is there anything I can do to earn a couple of breakfasts and a couple of drinks?"
"I don't know. Is there anything you can do?"
"What are we talking about?" Sam put the dirty dishes on the bar. "You offering us a job?"
"Not really." Bernard leaned back against the rear shelves and folded his arms. "Your friend here was asking for some food but hasn't any money to pay for it. I was asking him what you boys could so in exchange."
"We can fix computers." Sam nudged Dill with his shoulder. "Dill's brilliant at writing programs and finding bugs and I can build a computer out of a washing machine and a visit to the scrap yard."
"I haven't got a computer." Bernard stroked his chin. "But I do have use for a man who's good at finding bugs."
Dill frowned. "I thought you didn't have a com—"
"Brilliant!" Sam spoke to drown Dill's observation and grinned. "Lead us to it."
Bernard lifted up the bar access. "Step this way then. They're in the cellar."
