I do visit many places in my country and in the world. in my country, I took pictures & videos of people, with their permission, working in their areas like restaurants, cafes, etc…
I uploaded those pictures to Google Maps under the area where they work; then I start the training session.
Most of them, especially the expatriates, need to share their live videos or pictures with their families and loved ones in their home countries.
I do teach them how to use Google Maps if they did not use it before. I do teach them how to share their pictures to their families using the Share feature of Google Maps.
They are happy to know about that so they share their work location, information, and photos with their families.
It is a WIN, WIN, WIN situation. Google Maps win by getting popular among a big number of people, those workers win by sharing their pictures and videos with their families, I win by gaining more views on those pictures. Everyone is a winner here.
