Have you ever heard, lassi( yogurt-based drink from India) getting prepared in washing machines.
There is a 2008 print and television ad campaign for HSBC, written by Jeffree Benet of JWT Hong Kong, tells a tale of a Polish washing machine manufacturer’s representative sent to India to discover why their sales are so high there. On arriving, the representative investigates a lassi parlor, where he is warmly welcomed, and finds several washing machines being used to mix it. The owner tells him he is able to “make ten times as much lassi as I used to!”
This is commonly found practice of preparing lassi in Punjab region of India.
