Don't get angry; get even.
The last time they summoned me for parking "too long" at loading bay (I was there for like one hour. HDB estate.), I paid the fine.
But for the next three months, everyday, I make sure TP, LTA, Town Council and HDB ensured the roads are cleared of illegal parkings. I installed a temp CCTV at the balcony and called them whenever I see a car there.
On at least 20 occasions when they did not come promptly, I submit written complaints to the two Ministries and PMO.
Town Council officers finally came to meet me to "explain" their difficulities - crap manpower shortages etc. They also showed me figures that in those three months, they summoned at least 300 illegal parkings and another 300 warning.
Don't get angry. Get EVEN. I'm a taxpayer. F--k them where it hurts.
