ANYONE BELOW 160cm WILL NOT BE CHARGED. All 4 of them were very shocked as they did not know if they each had to pay for the MRT trip. They had no idea if they were all below 160cm. On top of that, they only have enough money to pay for 1 person for the trip. They all felt sad and disappointed especially so for Albert .

ANYONE BELOW 160cm WILL NOT BE CHARGED.

However, a nice Indian lady at the Station Control office saw the dismay on their faces and went up to them to offer her help. She assured them that she would help them find out about their heights so that they will know if they had to pay for the trip.
