Cucutta train ride with constant farting

I took a Train ride today through Calcutta to take in some scenery and Eastern culture. About ten minutes into the journey, a man got onto the train who looked like he hadnt washed all week and was in some type of scruffy pyjamas. Our carriage was already overly crowded. Two minutes later I sterted hearing these high pitched sqeaks and then hissing and chuffing noises coming from him. Then I got a whiff of the vilest smell I have ever encountered in my life. This man was openly and repeatedly farting. All the women did was pull their tops over their noses and carried on talking like it was nothing. Now, I am sorry, but anywhere elese this man would have been thrown out, but it is normal in Calcutta. Never again.
