As he was walking towards the escalator, a couple came down from the stairs.
The lady was wearing a straw hat which was rare in Singapore and the man had a map on his hand.
The teenager immediately recognized that they were Japanese tourists.
The Japanese lady was holding to two cans of milo and seemed to be looking for someone.
A middle aged lady staff in charge of crowd control at the train station platform looked at the Japanese couple intently as she walked passed time. Then she realized the lady was looking for a dustbin to discard her cans.
"There's no rubbish bin here," the staff shouted from afar.
The Japanese couple seemed not sure what they heard. The staff retaliated again when she saw they did not understood her.
Having studied Japanese language, the teenager turned to the couple and told them that there's no rubbish bin in Japanese. He turned and walked two steps before turning back to the couple and offered to help them dispose of the cans.
Seeing that they are tourists and were probably not aware that there's no rubbish bin in the platform, the staff could have offered to help them dispose the cans. Unfortunately, it's not part of her job scope.
If only she sees herself as a problem solver and her responsibility is to provide great customer experiences to commuters instead of crowd controller.
