Left-handers put the world to rights over a 'left-handed' cuppa at the GoodBean Coffee Shop at Blackwells, in Broad Street, Oxford, on Monday for Left-Handers Day.

Charlotte Martins, offers goodies and discounts to anyone proving their left-handedness, or sinistrality.

GoodBean also created an 'intelligent' tuna and roast pepper sandwich in homage to research suggesting left-handers are more intelligent than right-handers.

Alex Brardi, 28, of GoodBean Coffee, said: "Lots of people went for the intelligent sandwich so there will be lots of intelligent people walking around Oxford!"

Left-handed people make up about 10 per cent of the population, and have attracted a negative image over the years.
