The dhow is the boat that our forefathers took to migrate from Kutch, India to Zanzibar.
The joke is that It was fate that the winds were blowing south that we ended in Zanzibar otherwise we might have been in middle east somewhere!
There was a little display case where a glass top with a cupboard below where the retail date stock was stored to sell to customers. Our grandfather was very friendly and would invite all those who passed to come and have dates and Kahawa (coffee) to socialize. They said the retail date selling was a loss because most of it would be finished by the passerby! I suspect this is how the nickname came about.
