I've stopped purchasing anything from Sri Krishna Sweets (Vadapalani) except for the "Bengali" Sweets. I purchase them 'cos they appear _not_ to be contaminated with flies/insects due to the cold storage container that they are stored in. My repeated requests to the cashier/billing person to install full covers on the rest of the sweets/savories
sections have fallen on deaf ears.
FWIW, Adyar Ananda Bhavan (Vadapalani) has savories in cleanly closed containers. Their "Benagli" sweets are also in a cold container. Also, their other sweets are also placed in closed displays.
The next time, you visit Sri Krishna Sweets, take a few moments to talk to the cashier/billing person. Tell them that you are concerned about this apparent lack of concern that they have. And, more importantly, don't buy non-"Bengali" sweets from them. The irony is that their pricing is one of the highest !
Please take a stance to make a change for the better.
