thats new...
any house to house visits will have authorization letter chop by local police station.
last time ayam help collect donation also got this.

even they gomen opis ppl also should have proper identification policy esp want to go inside house and inspect.
since when gomen visitors simply can walk in and check house, without proper identification ?
even pulis also have to show their ID card to be acknowledged as pulis..

follow proper SOP lar. who know nowdays so many scammer/thief use gomen dress...
