People are complaining about the cost of petrol, at 1.20 pounds a litre. They should complain more about coffee, which costs at least 2 pounds. Every cup I’ve had has been uniformly dreadful, lacking in taste and flavour. And beer is 3 pounds a pint, which works out at more than 5 pounds a litre for lukewarm and flat brown water. Petrol requires a lot of processing from oil. Coffee and beer require minimal ingredients and are probably 80 per cent profit. No wonder London has so many pubs and coffee shops.
