Taste of inflation from a reliable sauceI am not sure where Bangkok stands in the list of most expensive cities released by the Economist this week. More to the point, even my hallowed HP Sauce has not been spared. It received the ultimate seal of approval in the 1960s when the British satirical magazine Private Eye adopted the name HP Sauce for its political column. French dressingA curiosity in those days was that part of the HP label describing the sauce was in French. It includes the immortal lyrics: "I think it's only fair/to point out that despite its faults/England still has HP Sauce."
