This is a brilliant move. Hope it is implemented properly. Earlier it was only in Rajdhani and Shatabdi trains. Now even in many AC express,superfast trains, the pantry staff, OBHS staff, and the person providing beddings come and ask for tips close to the end of the journey.
In fact in the CBE-Chennai Shatabdi express, remember the pantry guys coming with something like a donation box !!.....passengers used to drop Rs 10/20
The TIP culture needs to be curtailed.
