Was on a SMRT bus service today. Saw this sticker pasted on the
window at the wheelchair space area. The sticker say send the bus
service number and the bus captain name to 91841505.
Just for fun, I wrote a SMS saying "888 & Cai Sheng Ye" and
sent it to 91841505.
A few seconds later, they reply back with a SMS saying "Thank
you for your SMS! Your feedback will encourage our Bus Captains to
improve and provide better service. Thank you for travelling with
SMRT Buses."
