and every tour organizer is trying to keep a profit at the same time.
there are many ways to make profit, long term vs short term. Have you seen the movie Jerry Maguire?
"Right now, you are a paycheck player. You play with your head, not your heart. In your personal life, heart. But when you get on the field it's all about what you didn't get."
This is what is missing with the tour operators.
When you went all over to take picture (paid or not paid, doesn't matter) you were providing a service in exchange for money or goodwill. There is no shame in that. I would have done that. There are many people who does exactly that professionally, there is nothing wrong with that.
Any business can be grown as an engaging one. But most people don't understand it.
Have you watched প্রাক্তন movie? I wanted to be a tour guide not a organizer though!
Haven't watched that movie, should put my to-watch list.
