This is not a frivolous question. The issue of trust in business is a red-hot one at the moment and firms that are found untrustworthy by their customers and the public can pay a heavy commercial price, which might savage their bottom line.
Our article on trust gives the vexed question a thorough airing, right from the crisis that has befallen the poor old BBC - its staff are wearing hairshirts after 'Crowngate' and the voting scandal that attended the naming of the Blue Peter cat - to why globalisation might have loosened the emotional ties between business and society. There's no doubt that the relationship between my mother and her grocer down the road in the 1960s was very different from what exists between the Gwythers and their supermarket now.
I find the whole debate slightly bewildering. I don't particularly trust those who provide me with goods and services - Ryanair, my barber down by Hammersmith tube station, Pret A Manger, where I get my lunchtime sandwich, or Lambeth Council, which takes away my rubbish each week and makes me wait a month to register the birth of my child. But that doesn't mean I despise them or find them dishonest. They can make mistakes that irritate me, but I'd hope that they're just trying to do an honest job.
