Chitale Bandhu Mithaiwala

My brother in law is virtually a Punaikar having worked there for four decades. He is back in Bangalore post retirement.
He went to Pune recently and brought back Chitale Bahdhu's famous Kesar Srikhand which is marginally upstaged by their Aama Srikhand. These were rounded off by Bakarwadi.

While I did appreciate all three from the old Chitale house, the engineer in me was also impressed by the modern billing process adopted by this traditional dairy people.
It seems there is a big crowd at their Deccan Gymkhana shop in Pune. As you enter you are givena largish plastic sheet. At each counter the attendant places this sheet on a pad and enters the item and quantity and returns the pad. The process is repeated at every counter that you visit. At the check out counter the pad is laid on the reader, which prints an itemised bill.
