Working for free and earning for tips. I few days ago somebody told me about a news of a young couple that decided to quit to their office job and started an idea called: free tours in Spain. This guys decided to start a free tour program. They announced on their instagram called “dunky tours” where is the point to begin the tour by different walking around the city. The first time they only had 7 people. Then they started to have bigger groups. The guys worked as a lawyers. They had a typical routine with a 9 to 5 job and earned per month around €1000. With this idea and the implementation of the “free tours around a city Of Spain” they can earn a net income of €2500 working 3 times per week. But here is a thing, they earn that quantity of money with the tips that given them “potencial clients”, because the tour is “free”. In the long term, I don’t know if this idea is sostenible during the time. Maybe for a break of the office routine it is a good option. But who knows?.
