It’s a familiar feeling. You feel full, a little drowsy. The meal you have just finished was surprising and delicious in equal measure. You don’t consider yourself too much the foodie or the wine snob but recognise that both, in this case, were excellent. The evening is in its adolescence so, after glancing at the time, you motion for the bill. In our little container, the bill comes folded into a kind short fat cigar, paperclipped to two cards - one business, one charity.
