Well, there are many scammers around us. We just need to be aware of the things happening around us. They are very fast and intelligent in their approach. They can be drivers, watchmen, salesmen etc. It's not safe to share our personal stuff or information with the strangers. They can do some frauds or something like that. They can also sell your information just for the sake of money or utility benefits. Reporting the taxi cab service is good but it is not a permanent solution. They are everywhere around us. Maybe they are working in companies or groups.
