No parking is no stopping?

No parking is no stopping?

From Media Indonesia

As part of my daily routine, I stopped my car recently in front of Plaza Mandiri, Jl. Gatot Subroto, to drop my wife and a friend working in the BEJ commercial area. I was sure that stopping in this area was allowed because there was only a no- parking sign.

A policeman suddenly appeared, asking me to give up my driver's license for ticketing. I tried to explain that not a single no-stopping sign was found, so there was no violation. I also argued that the engine of my car was still running and I had stopped for less than a minute. But he insisted by forcing me to sign the ticket for a fine.

As an obedient citizen, I was dissatisfied with such arbitrary treatment. If there is indeed no difference between the prohibition on parking and that on stopping, why are two traffic signs still used instead of just one?
