I think the funniest and most embarassing story I have about travel in India: The first day in downtown Mumbai, I go to the train stain to buy a ticket for a Churchgate station a few stops away. Honestly, I have no idea what the price will be, but I assume 20-30 rupees. I only have 100 rupee notes. I go to the ticket window: Lady tells me: "5 rupees". I gasped, and looked at my 100 rupee note. She rejects my 100 rupee note! (She was not disrespectful; said: you will take all my change! Wait here; after next person, I can sell it to you.) Next person pays with enough change, then me. All good. We both laughed. To put that in perspective, that is about 2-3 Euro CENTS to ride the train!
Edit- echoing a comment further down. I got an Indian visa. It was done online and was emailed to me in 24hrs.
