IIs it common to bring little gifts and presents to the local, poorer inhabitants?
In many South American countries, tourists like to carry little gifts for the local population. Also in Peru there are many poor people, both adults and children, that are begging or selling sweets in the streets. Especially children are of course happy if you give them little presents but you should be careful with giving them sweets. In many places this has already exceeded limits and children are suffering from bad teeth. We would recommend to rather buy some fresh fruit or bred once you are there and give it to them.
