Young souvenir vendor inside Ta Prohm

Local children often duck the security into Ta Prohm (an easier feat here than at other temples) and offer to buy souvenirs or to guide you through the temple.
In my experience the reason why young kids see the opportunity for a better income at tourist places: most visitors poor the kids and they are generously in spending out too much their money for unnecessary twaddels.
