Jackfruit has a great, rich taste; I like it, although I don't go much for sweet foods generally (I make an exception now and then, for some). The sticky stuff between the edible parts is a bit of a turnoff, though. Not easy to get it off your hands, once on. Also, the fruit has a strong smell, but not a bad one, IMO.
You cannot eat a lot of it, since it is rather dense, though soft.
It's also one of those wonder plants, like neem, banana and coconut, with many uses.
Loss from stealing was called 'shrinkage' by retail industry people, in Sam Walton's autobiography 'Made in America'. As you say, they expected to have some. I wonder why it can't be prevented 100%.
Prevention to 100% would be costly. They have diminishing marginal returns.
Why would someone pay $50,000/year for a hypothetical system which would theoretically catch everyone and fill out the police report automatically when the store experiences a tiny $300 annual shrinkage loss?
Lying for Money makes the case that the optimal amount of fraud in any real world system is non-zero. Fraud prevention has direct and indirect costs. At some point the costs of fraud prevention will exceed the cost of fraud itself.
