A prosperous shopkeeper is asked by his little grandson, 'Grampa, what does honesty mean?'
Grampa chooses his words carefully. 'Suppose a customer overpays me Rs. 100. I should share half of this with my brother, who runs the shop alternately with me. He would never have known if I hadn't told him, but I should. That's honesty.'
'But grampa - what about the customer? He overpaid, didn't you say? Shouldn't you...'
'Don't bother about the customer, boy. That's not our concern. He ought to have been more careful.'
[I got this gem from a little book of witticisms written in Bangla by Tarapada Ray. And I shall be the first to admit that I know a lot of shopkeepers who are not like that!]
