Customers were all expecting to get milked, sure. But the milking process usually tries not to kill the cow.

Usually that means prices increasing by ~10% every year, so that it's never quite worth it to switch to an alternative system.

Sounds like customers were not familiar with how Mr Tan plays ball, he's been doing this forever. He isn't trying to kill the cow, he will famish the cow to the point where the cow will be alive enough for him to milk his required rate of return and not an ounce more. Its a risky strategy, but Tan is loved by Mr Market so he gets the benefit of the doubt.
