My only tryst with rail staff was when I was going to Jhansi. They had occupied whole of AC 3 Tier despite train having nearly 10 SL coaches. Apart from singular AC 2 Tier, where they dared not enter because of presence of TT, they didn't leave any place untouched. And they wouldn't leave until you threaten them with complaint. One person even came and asked me at Kanpur if he can ride only till Jhansi. The train went terminated at Gwalior. If you are sharing a seat for 80% of the ride, it is not "ONLY".
