RANT ALERT!!!!!
I found this letter truly OFFENSIVE. This is typical Indian food you're talking about.
O.K. So airports don't actually supply food that is recogdnised by everyone. The "yellow spongey things" is called "Dhokla" and the "green paste" is actually Chutney. I take that all of you know what chutney is!.
O.K. So your local restaurant doesn't have these dishes on their menu. These dishes differ from region to region in India. The person who made it probably isn't aware of how finicky plane passengers are.
To complain like this is an insult to all Indians/Bengalis/Pakistanis. Basically anyone whose traditional food includes lots of herbs and spices and unusual dishes.
What I want to know is what that particular passenger was doing flying from Mumbai, when he clearly cannot stand Indian food?
Maybe he could have stated when he checked in that he would like a specific menu.
One that includes Boiled Cabbage, boiled broccolli, boiled carrots and grilled chicken.
