K.Udomchai stays at smoking area because I know that he is CP guy, I do not want him to entry process area then I asked K.Pichet to interview and dig deep detail who is he? And finally he told K.Pichet who he is.
If I do not know him before, he will entry plant because NCH has work to clean scalded plate which inside plant. However in the past if I know any supplier has not clear his status I will punish him ie ban him for a few month.
Recently we ban Nut service who do PM for FP2 3 months, more detail you can check with your team. This case we need to do something to let NCH aware on this point.
