"I used to nick Mars Bars from the Spar," Allan said, making a face, "because the bigger boys said the shop man was a Prot and a bastard. Then one night they torched the place and it's a car park now. I kinda regret it because I'm betting he was an okay guy in his own way. He didn't deserve that. If I have to have chocolate then - I guess the dark kind in big fancy bars - and I can use it to bribe Chas to do my days when I'm having more fun doing summat else." He grinned. "So what's your favourite, then? What's the kinda chocolate that you'd do anything for. I promise I won't tell a soul."
