There are people who get off trains in Bucharest. There is some difficulty in getting from the train to the Taxi. Yet, there are few people who would help you at that moment. This is a business opportunity.
While in trains, you see from time to time people begging, in various forms, with various scenarios. This is not a business opportunity, but likely make lots of people who are travelling more annoyed.
How come the people who go begging in trains don’t notice the business opportunity of helping others to get from the train to the bus/taxi/another train, while in the train stations?
It makes you think of what they would be capable of doing to get money – help others? Not so much. Annoy a lot of people in the trains. That is fine.
