Efficient Singapore

How efficient is Singapore's Land Transport Authority (LTA)? I noticed a pedestrian crossing traffic light at a road junction near my house was 90 degrees out, perhaps having been hit by a lorry, so I emailed LTA. I told them that the green man was now facing the entrance to Tanglin Trust School's sports field and was inviting kids to walk out into four lanes of speeding traffic. Not good. Anyway, the LTA fixed the light within about 4 hours of me sending the email, somebody from LTA called me to confirm the light had been repaired and, I believe, we didn't lose any kids from Tanglin Trust School. Job done.
