Where is the chai man?

 When you’re snoozing on the train you are constantly disturbed  by the sound of the chai, paanee (water) and food sellers. Our journey from Varanasi should have taken 13hours. I set my alarm for 6.30am to have enough time for a loo visit and get the luggage out for the quick 5 minute train stop at Agra Fort station. However no one was stirring in the carriage and the Where is my train app showed a delay of 4 hours. Eventually we go in at 1.20pm - and before that had a very long wait for the chai man. Eventually when he arrived we order two each and the very generous army guy sat near us paid for them. The kindness of strangers.
