That Im sure is a Thai thing..... Grab theys alway beleive what the app says, even if you send them photos and maps(which they dont like) proving it, then hang around the pin untill food is cold.. I close the gate then wait for headquartars to call so I can vest on them, but they again thai thinking, only concerned I received the Grab food and never care my address is pinned wrong for over one year.. unchangable, so Panda gets all my business.. no problem..
