Arshad Warsi had most bad experience while shooting for his next upcoming film 'Kabul Express' in Afghanistan. "Beside security, there were other problems like the weather. The temperature would be tolerable and then, all of sudden, it would drop to around minus 15 and there would be sand everywhere, even in your food. Moreover, for food, you have to survive on only meat. For vegetarians there was only chana. Now, how much of meat and chana can one eat? It was a big problem for someone like John who's staunch vegetarian. Poor guy, he couldn't adjust and fell ill," shares Arshad.
