When you get a crappy job with tiny pay so you do less work for the same pay as the other guy. Anything from playing Nitrome on an office computer when no one's looking to taking 10 minute vape breaks to watching funny videos. When the pay is increased, you do more work so you no longer milk the cow.
I'm getting payed 30 dollars for helping to fix a basement for 3 hours, might as well be milking the cow. Vape break!

Milking the cow can be used to describe attaining the absolute most from any given situation.

Sometimes called 'milking the cash cow', 'milking the cow' can also be applied to any franchises which continue to drain the public of as much cash as possible and attempt to attach the brand name to absolutely everything, be it cereal, video games, car adverts, tshirts, bedsheets, plush toys, action figures, computer accessories or anything else that would be seemingly unrelated.
