How surveillance is used to extort money while purchasing potatoes offline

One of the advantages of the online websites like bigbasket, naturesbasket is that there is a lot of transparency in the pricing of items listed for sale. Small retailers are extorting any money they wish to, in Panaji, goa after putting the domain investor under surveillance, reading her memory. For example the price of 1 Kg of potatos on online websites is Rs 19 on May 24, 2017.
However when the domain investor, google competitor went to a small retailer to purchase potatoes as requested by a relative, the retailer quoted a price of Rs 48 for 1 kg on May 24, 2017. It would be interesting to find out which intelligence employee had asked the retailer to quote a highly inflated price from the domain investor. At another shop in the same area, less than 100 m away, the retailer was quoting a price of Rs 20 per kg. This is a clear indication of how memory reading is misused to extort money from the already broke domain investor by the google, tata sponsored fraud R&AW/CBI/indian intelligence employees who are impersonating the domain investor.
