The valid reason from Khun Boonmee is;
On the way back from delivered the belonging of guest room 209 and 233 ,Khun Kwang, room maid asked him to help other maid clean the room, before he want he has call to check the viability with friend at the porter counter then he decided to help the maid to clean the room and set up the bedding.
I was advised the head hall Porter how to do when it’s happen next time.
