If you travel in trains from Howrah and Sealdah, you will find a number of fittings missing including even bathroom windows which cannot be fitted in anyone's house. Even if they don't work in your home, they can always be sold by weight for the material value even if one fan will fetch you only 5 rupees. When somebody writes from experience don't rush to counter what is written. Just because you have not experienced something DOES NOT MEAN that nobody else has or should have experienced it.
