I lived in an apartment complex for 8 years. I am partially disabled, and have handicap plates on my vehicle. Upon request, the apartment complex painted and marked off an extra handicap space for me. There was already another handicap space in the same area, so they had 2 in the same area, after creating one for me. The tennant who used the original spot decided they preferred the new spot, and began parking there. No big deal, but they later began parking over the line so I could use neither space. Requests from the complex yeilded no improvement in the situation. So, in the evenings, I'd put on a disposable glove, and pour a handful of honey. I adorned all the door handles with sticky grossness, then squirreled petroliam jelly on the windshield. The parking issue ceased to be an issue. Mysteriously, shortly that Tennant moved away.
A month or so later, someone without handicap tags began to park a land yacht straddling the line. I treated this visitor to the same car accents. But the apartment complex didn't recognize the tag number. It was likely a guest. They'd leave that tank parked badly for up to a week. I was looking to buy a house, but determined to get even. I bought myself a full sized SUV, and used my car, and SUV to occupy both spots. Problem solved! The complex removed both handicap spots when I moved out.
