I am very sorry, if i sound rude or unpleasant.... i want to tell u something.. its a request.. please refrain from eating spicy foods or that contains heavy masala in A/C coaches..The smell spreads in whole coach in a jiffy..it is uncomfortable to atleast some passengers.. i know its not practical for long distance travellers.. i am just bringing it to notice.. I found it very uncomfortable when i travelled recently to bangalore! please we can do it atleast in case of short travels ie, starting at evening and that ends with a one night..
