I stay in Pune, India and my family uses cow milk. I dont get promotions or salary hikes easily.
Reason: As you all know, in India, cow milk contains less fat... and companies in Pune remove all the cream...
Less fat means less cream and less cream means you get less butter.
And in India promotion ya salary hike ke liye makkhan lagaana padta hai. So less butter means no promotions.
So switch to buffalo milk if you want promotions or salary hike ;-)
